Top Female Boxers of All Time: The Greatest Women in Boxing
On this page16
Placement here rewards undisputed status over single belts, unbeaten or near-unbeaten records over padded ones, quality of opposition, and measurable commercial impact — arena size and broadcast reach — over name recognition alone. Amateur medals count, but professional undisputed titles carry the most weight.
- Undisputed x3 · P4P #1
Claressa Shields
Shields is the only boxer of either gender to hold undisputed titles in three weight classes. She was already undisputed at light-middleweight and middleweight when, in February 2025, she beat Danielle Perkins to add the heavyweight belts and become boxing's first three-division undisputed champion. No other woman pairs that with two Olympic golds.
She won gold at London 2012 as a 17-year-old and again at Rio 2016 — the first American boxer of either gender to win consecutive Olympic golds — then turned professional and never lost. That amateur-to-pro dominance is why she sits above Taylor, who has undisputed titles in two divisions rather than three.
Country: USA · Olympic gold: 2012, 2016 · Undisputed at: 154, 160, heavyweight
- Two-weight undisputed
Katie Taylor
Taylor became undisputed at lightweight and later at super-lightweight, and won her trilogy with Amanda Serrano 3-0 — a split decision in 2022, a unanimous decision in 2024, and a majority decision in July 2025. Their first meeting was the first women's bout to headline Madison Square Garden.
She ranks above Serrano on head-to-head results and undisputed status in two divisions. Before turning pro she won Olympic gold at London 2012 and multiple World Amateur Championship golds, making her one of the few on this list who dominated both codes.
Country: Ireland · Olympic gold: 2012 · Undisputed at: lightweight, super-lightweight
- Seven-division champion
Amanda Serrano
Serrano holds a Guinness World Record for world titles across seven weight classes, more divisions than any other female boxer, and became the first woman to be undisputed at featherweight. Her volume-punching style — she routinely out-throws opponents — made her the sport's busiest elite fighter.
She sits behind Taylor only because she lost all three of their fights on the cards, several by razor-thin margins that split opinion. She remains active and ranked among the top pound-for-pound fighters in 2026.
Country: Puerto Rico · Record: 7 weight-class titles · Undisputed at: featherweight
- Unbeaten 24-0
Laila Ali
Muhammad Ali's daughter retired 24-0 with 21 knockouts, unbeaten across super middleweight and light heavyweight, where she collected titles including the WBC and IWBF belts. Power carried her career: nearly nine in ten wins came inside the distance.
She fought from 1999 to 2007, an era with far less television support for women than today, yet still pulled network broadcasts and mainstream attention to the sport. Her perfect record places her alongside boxing's other undefeated fighters.
Country: USA · Record: 24-0 (21 KO) · Titles: super middleweight, light heavyweight
- Record undisputed reign
Cecilia Braekhus
Braekhus held all four major welterweight belts at once for roughly six years (2014–2020) — the longest uninterrupted undisputed reign of the four-belt era for any boxer, male or female — inside an 11-year run as welterweight champion. Her game was ring IQ and precision rather than knockout power.
Her reign ended in a disputed August 2020 decision loss to Jessica McCaskill, as she chased a record 26th straight title defense. Ranking her fifth reflects a thinner talent pool at 147 pounds in her era than the divisions above her fought in.
Country: Norway · Undisputed: 2014–2020 · Reign: all four welterweight belts
- Never beaten
Lucia Rijker
Rijker retired 17-0 with 14 knockouts and was never beaten in boxing or in a long kickboxing career, earning the nickname "The Most Dangerous Woman in the World." She held the WIBF super-lightweight title and dominated a crossover résumé that connects boxing to kickboxing.
Historians and trainers still cite her on pure dominance, even though casual fans know Ali and Taylor better. She sits sixth rather than higher because her competition and title depth were thinner than the modern undisputed champions above her.
Country: Netherlands · Record: 17-0 (14 KO) · Also unbeaten in kickboxing
- Trailblazer
Christy Martin
Martin did more than almost anyone to put women's boxing on American television, headlining undercards on Mike Tyson pay-per-views through the 1990s when networks wouldn't touch the women's game. Her 1996 win on the Tyson–Bruno card is often marked as the sport's mainstream breakthrough.
She was elected in the Class of 2020 — the first year women appeared on the International Boxing Hall of Fame ballot — and inducted in the delayed June 2022 ceremony alongside Barbara Buttrick and Lucia Rijker. She ranks on impact more than record.
Country: USA · Active: 1989–2012 · IBHOF: elected 2020 (first women's class)
- Longtime champion
Regina Halmich
Halmich finished 54-1-1 and held a WIBF flyweight world title for well over a decade, with her only loss coming early, in 1995. She filled arenas in Germany when women's boxing struggled to draw a crowd almost anywhere else.
Her fights were regularly among the highest-rated sports broadcasts on German television — a commercial pull few of her contemporaries matched. That domestic dominance, against limited international opposition, is why she lands eighth rather than higher.
Country: Germany · Record: 54-1-1 · Title: WIBF flyweight (10+ years)
- Olympic pioneer
Nicola Adams
Adams was the first woman to win an Olympic boxing gold, at London 2012, then the first to defend it at Rio 2016. She turned professional and won the WBO flyweight title in 2019 before retiring later that year over vision concerns, ending 5-0-1.
Her professional résumé is short, which caps her ranking, but her amateur firsts reshaped the sport in Britain and drove a wave of new participation at home.
Country: Great Britain · Olympic gold: 2012, 2016 · Pro: WBO flyweight
- Amateur icon
Mary Kom
Kom is the only boxer to win the World Amateur Boxing Championship six times, across a career spanning more than two decades, and added an Olympic bronze at London 2012. Her longevity at the elite amateur level is unmatched in the women's game.
She ranks tenth because her career was almost entirely amateur, without the professional title reigns that define the fighters above her — but no one has matched her staying power on the world stage.
Country: India · World Amateur titles: 6 · Olympic bronze: 2012
- Boxing-to-MMA
Holly Holm
Before she knocked out Ronda Rousey in the UFC, Holm was a multi-division professional boxing champion, holding welterweight titles and belts sanctioned by the WBA, WBC and IBF across weight classes. Her footwork and output — the same tools that stunned MMA — made her one of the most technically complete boxers of the 2000s.
Her boxing peak overlapped a thin era for televised women's bouts, and she left the sport in 2013 for MMA, which limits her ranking against fighters who stayed and built longer title runs.
Country: USA · Boxing: multi-division champion · Retired boxing: 2013
- Rising star
Gabriela Fundora
Fundora is the newest name here and the one most likely to climb it. In November 2024 she became the youngest four-belt undisputed champion in history, and she entered 2026 as the reigning undisputed flyweight champion, unbeaten and defending regularly.
She ranks twelfth on résumé length, not ceiling: her body of work is still young next to the veterans above her. She headlines a generation — alongside Mikaela Mayer and Lauren Price — carrying the sport's momentum past the Taylor–Serrano era.
Country: USA · Record: unbeaten (18-0 in 2026) · Undisputed at: flyweight

Audience ranking
How everyone ranked them
Built from reader rankings using position-based points.
Ask ten boxing fans to name the greatest female fighter and you’ll get at least three different answers. Women’s boxing didn’t have an Olympic stage until 2012, so ranking across eras means weighing amateur medals against professional belts, and a fighter who never lost against one who fought everyone available. The cards above are the actual ranked leaderboard, with the record behind each name; the sections below explain how they were weighed and where the comparisons get genuinely hard.
How we ranked these boxers
Four factors decide placement, in rough order of weight:
- Titles actually held. Undisputed status — all four major belts at once — counts far more than a single sanctioning body’s belt. Shields (three divisions), Taylor (two), Serrano, Braekhus, and Fundora all cleared this bar.
- Record and unbeaten runs. A perfect or near-perfect record against real opposition matters, which is why Rijker (17-0), Ali (24-0), and Halmich (54-1-1) rank highly despite older, thinner talent pools.
- Quality of opposition. Head-to-head results break ties. Taylor sits above Serrano because she won all three of their fights.
- Measurable impact. Arena size, broadcast reach, and whether a fighter moved the sport commercially. This is what earns pioneers like Martin and Halmich their spots.
Boxing’s scoring system and its 17 weight classes apply to the women’s ranks exactly as they do the men’s, which is part of why cross-division comparisons are so contested.
Amateur medals vs. professional belts
The single biggest complication in any women’s boxing ranking is that the sport’s structure changed mid-career for almost everyone on this list. Sanctioning bodies barely recognized women until the late 1990s, and the Olympics didn’t open the door until London 2012.
That timeline splits the field. Mary Kom and, for most of her career, Nicola Adams built their cases in the amateur ranks, where the reward is world championships and Olympic medals rather than professional belts. Laila Ali, Lucia Rijker, and Regina Halmich fought almost entirely as professionals in an era with limited television support. Only the most recent generation — Shields, Taylor, Serrano, Fundora — got to stack Olympic pedigree and undisputed professional titles in the same career, which is a large part of why they cluster at the top.

Where this list is most debatable
The top three are close enough that reasonable people reorder them. Shields leads on undisputed titles in three divisions, but Serrano lost all three Taylor fights by tight margins that several outlets scored the other way — flip one of those cards and the 2–3 order changes. Rijker and Ali could each sit higher than fifth on pure records if you weight unbeaten dominance over division depth; they’re held down mainly by the thinner fields they faced. And Fundora is the one name likely to move: entering 2026 unbeaten and defending regularly, she has the clearest path to climbing.

Frequently asked questions
Who is considered the greatest female boxer of all time?+
There's no single answer. Claressa Shields tops most current lists after winning undisputed titles in three weight classes plus two Olympic golds. Historically, Lucia Rijker is named the greatest on pure dominance, retiring 17-0 and never beaten in boxing or kickboxing. Katie Taylor and Amanda Serrano sit just behind Shields on the strength of their multi-division titles and the trilogy that dragged women's boxing into the pay-per-view mainstream.
Did Katie Taylor or Amanda Serrano win their trilogy?+
Katie Taylor swept the trilogy 3-0, though every fight was close. She took the first by split decision in 2022, the second by unanimous decision in 2024, and the third by majority decision in July 2025. The 2024 and 2025 results split opinion, with many observers scoring for Serrano's higher output. The rivalry is still the commercial high-water mark for women's boxing, and their first bout headlined Madison Square Garden.
Which female boxer has held world titles in the most weight classes?+
Amanda Serrano of Puerto Rico holds a Guinness World Record for world titles across seven weight classes, more than any other female boxer, from super flyweight up to featherweight, where she became the first woman to be undisputed. That range is her signature achievement and set her apart in the modern women's game long before her rivalry with Katie Taylor made international headlines and record-setting broadcast numbers.
Has any female boxer retired undefeated?+
Yes. Lucia Rijker retired 17-0 and was unbeaten in kickboxing too. Laila Ali finished 24-0 with 21 knockouts across super middleweight and light heavyweight. Nicola Adams ended her pro career 5-0-1. Regina Halmich came close at 54-1-1, her only loss coming early in 1995. Among active fighters, Gabriela Fundora and Claressa Shields both remained unbeaten as they moved through 2026, though their careers are still ongoing.
Who was the first woman elected to the International Boxing Hall of Fame?+
Women first appeared on the ballot for the Class of 2020, and Christy Martin, Barbara Buttrick, and Lucia Rijker were elected together, then inducted in the delayed June 2022 ceremony. Martin is the most-cited of the group for bringing women's boxing to mainstream American television on 1990s Mike Tyson undercards. Laila Ali followed in the Class of 2021, extending the sport's overdue recognition at Canastota.
When did women's boxing become an Olympic sport?+
Women's boxing debuted at the London 2012 Olympics, decades after the men's event. Britain's Nicola Adams won the first women's Olympic boxing gold there and defended it at Rio 2016. Claressa Shields also won gold at London 2012 and again in 2016, becoming the first American boxer of either gender to win consecutive Olympic golds. That 2012 debut is the dividing line for comparing amateur eras in the women's game.
