Most Home Runs by a Team in a Season
On this page4
The 2019 Minnesota Twins hit 307 home runs, the most by any team in a single MLB season. They finished one ahead of the 2019 New York Yankees, who hit 306, and both blew past a record that had stood at 267 for exactly one year. The “Bomba Squad” nickname stuck because no lineup had ever slugged like that over a full season.
The number is a team total, every home run across the whole roster added up, which makes it a different record from the single-season mark for one hitter. Here is the full table, the reason 2019 rewrote it, and why 307 has looked safe ever since.
Most home runs by a team in a single MLB season
The table ranks the top team home-run totals in a single season. The 2019 season dominates the list.
| Rank | Team | Season | Home runs |
|---|---|---|---|
| 1 | Minnesota Twins | 2019 | 307 |
| 2 | New York Yankees | 2019 | 306 |
| 3 | Houston Astros | 2019 | 288 |
| 4 | Los Angeles Dodgers | 2019 | 279 |
| 5 | New York Yankees | 2018 | 267 |
| 6 | Seattle Mariners | 1997 | 264 |
The list is almost entirely one year. Four of the top six totals come from 2019, and the two records below them mark the steps that led up to it: the 2018 Yankees’ 267, which broke the 1997 Mariners’ 264 after two decades. Then 2019 erased both in a single summer.
The 2019 Twins and the Bomba Squad
Minnesota’s 2019 team spread its power across the lineup rather than leaning on one or two sluggers. Five players hit at least 30 home runs, a first in MLB history, which is how the total climbed to 307 without a single hitter approaching the season player record. The nickname captured the style: relentless, top to bottom, home run after home run.
They edged the Yankees by one, a fitting margin in a season when both teams were rewriting the record together. It was a race decided in the final days, and the Twins came out a single swing ahead.
Why 2019 rewrote the record
The main reason was the ball. Testing showed the 2019 baseball had lower drag, so fly balls carried farther and warning-track outs became home runs. Layer that over a league-wide shift toward launch angle and power hitting, and every team’s total rose at once. The whole of MLB set a home-run record that year, not just the Twins and Yankees.
That also explains why the record looks so durable. After 2019, the league adjusted the ball, and top team totals fell back into the 240s and 250s. The conditions that produced 307 have not returned, which is why the Bomba Squad still sits alone.
Team record versus player record
Keep the two apart, because fans mix them up constantly. The 307 is a team figure, the sum of a whole roster’s home runs. The single-season record for one player is Barry Bonds’ 73 in 2001, a completely separate mark with a different holder and a different story.
For the individual side of the ledger, our page on the most home runs in a season covers Bonds’ 73 and the crowded chase behind it. One record measures a lineup; the other measures a single, historic bat.

The short version: the 2019 Minnesota Twins’ 307 home runs is the MLB team single-season record, one ahead of the 2019 Yankees, and both stand far clear of everything before or since a uniquely powerful season.
Frequently asked questions
Which team hit the most home runs in a season?+
The 2019 Minnesota Twins, with 307 home runs, the most any MLB team has hit in a single season. Nicknamed the Bomba Squad, they set the mark in a year of record power across baseball, edging the New York Yankees, who hit 306 the same season. No team has reached 300 in a season since 2019.
How many home runs did the 2019 Yankees hit?+
The 2019 Yankees hit 306 home runs, one behind the Twins and the second-highest team total in MLB history. Both teams shattered the previous record of 267, which the Yankees themselves had set just a year earlier in 2018. The two 2019 clubs are the only teams ever to pass 300.
Why did teams hit so many home runs in 2019?+
A livelier baseball with lower drag was the biggest factor, letting fly balls carry farther, on top of a hitting approach built around launch angle and power over contact. The whole league set a home-run record that year, so the team totals rose together. MLB later adjusted the ball, and totals came down.
What was the home run record before 2019?+
The 2018 New York Yankees held it with 267, which had broken the 1997 Seattle Mariners' 264. That 264 mark stood for over 20 years, so the jump to 307 in a single season was a dramatic leap. Two decades of gradual progress were erased in one year.
Is the team record the same as the player record?+
No, they are separate. The team record is the Twins' 307 in 2019. The single-season record for one player is Barry Bonds' 73 in 2001. A team total adds up every player's home runs across a lineup, while the player record is one hitter's output, so the two numbers and holders are unrelated.
Has any team come close to 307 since 2019?+
No. After MLB adjusted the ball, team totals fell back into the 240s and 250s for the top power lineups. Several clubs have led the league with strong home-run seasons, but none has threatened 300, leaving the 2019 Twins and Yankees alone above that line.
