The 10 Longest Home Runs In MLB History

Today we are counting down the 10 longest home runs in MLB history, from Mo Vaughn to Babe Ruth. Several of these home runs cleared the ball park but only one went off the score board.

This list of the longest home runs in MLB history is filled with baseball legends like Babe Ruth and Mickey Mantle, as it should be. There is, of course, some subjectivity to this list as older home runs were more difficult to measure and the two longest HRs of all time are from generations ago so who is to say the legends haven’t grown over time?

Leading off the list of the 10 longest home runs in MLB history below is Mo Vaughn. The list gets rounded out by the Great Bambino.

I had a lot of fun remembering some of these epic feats by baseball’s greatest sluggers and I hope you will enjoy reading about them.

T9. Mo Vaughn: 505 feet

On June 26, 2002, Mo Vaughn hit a 505-foot home run at Shea Stadium in Queens and it is tied for the 9th longest HR in MLB history. Mo Vaughn was a legendary home run hitter with power most players could only ever dream of and this was the best HR of his career.

This was, as far as I can tell, the only home run on this list of the 10 longest homers in MLB history to be hit off the scoreboard.

T9. Nomar Mazara: 505

In 2019 with the Texas Rangers, right fielder Nomar Mazara hit what is tied for the 9th longest home run in Major League Baseball history at 505 feet, as measured by Statcast. Trevor Story also has a 505-footer as measured by Statcast so he deserves a mention here as well.

Mazar’s 505-foot HR came in the first inning in a game the Rangers would lost 5-4 in 10 innings. It is the longest home run ever measured at Globe Life Park in Texas.

8. Jim Thome: 511 feet

On July 3, 1999, Cleveland (Indians) slugger Jim Thome crushed the 8th longest home run in MLB history at 511 feet in a game his team would win 9-8 during a doubleheader against the Kansas City Royals at Jacobs Field.

Thome’s 511-foot home run came on a 3-1 pitch and went over the left center field wall and it landed in the tippy top of the bleachers before hopping out of the park and onto Eagle Avenue.

7. Darryl Strawberry: 525 feet

On April 4, 1988, Darryl Strawberry launched a 525-foot home run, the 7th longest home run in MLB history. This home run was interesting because Strawberry, one of my all-time favorite players, hit his 525-foot home run off the concrete ring at Olympic Stadium in Montreal, the former home of the Montreal Expos.

There was some minor controversy around whether the ball was fair or foul because it was hit so far, but it was ultimately ruled fair and the 7th longest HR in MLB history.

6. Dave Kingman: 530 feet

Against the Chicago Cubs on April 14, 1976, Mets slugger Dave Kingman launched the sixth longest home run in MLB history which was officially measured at 530 feet. That said, some believe it was the longest homer in Major League Baseball history and claim it measured 600 feet, though the record books say differently.

There was reportedly a 35 MPH wind helping balls jump out of the park that day which aided his legendary homer.

T4. Willie Stargell: 535 feet

On May 20th, 1978, Hall of Famer Willie Stargell smashed what stands now as (tied for) the 4th longest home run in MLB history and the longest home run ever hit at Montreal’s Olympic Stadium, the former home of the Montreal Expos.

Willie Stargell was unstoppable at the plate that season and right-hander Wayne Twitchell just happened to be in the way of Stargell chasing home run records that day. He started the game with a 3-run HR in the 1st inning and then in the 4th inning with one runner on, Willie Stargell would hit his 535-foot dinger and make history.

T4. Adam Dunn: 535 feet

Cincinnati Reds slugger Adam Dunn hit a 535-foot home run against the Dodgers on August 10, 2004, tying him for the 4th longest home run in MLB history.

Dunn was facing Dodgers pitcher José Lima and hit the stripes off the ball in the fourth inning. It stands as the longest hoem run ever hit at Great American Ball Park in Cincinnati.

3. Reggie Jackson: 539 feet

Reggie Jackson’s 539-foot home run in 1971 was the third-longest home run in MLB history and it carries an interesting caveat: he hit it during the MLB All-Star Game that year.

The home run came at Tiger Stadium in Detroit with a 30 MPH wind blowing that night. Dock Ellis was pitching, supposedly on more than water and caffeine, and the rest was history.

2. Mickey Mantle: 565 feet

With the second-longest home run in MLB history, 32 years after the longest dinger in baseball history, New York Yankees legend Mickey Mantle hit a 565 foot homer on April 17, 1953, two years to the exact day from his MLB debut.

Mickey Mantle’s legendary home run came in the top of the 5th inning with a 2-1 lead over the Washington Senators. Yogi Berra had just walked and Mantle was looking to extend the inning but here’s where it gets wild: he had to borrow a bat.

For the second-longest home run in MLB history, Mickey Mantle borrowed a teammate’s bat and then hit a 565-foot home run off left-handed pitcher Chuck Stobbs.

1. Babe Ruth: 575 feet (1921)

Babe Ruth’s 575-foot home run in 1921 is firmly in the MLB record books as the longest home run in MLB history by a full 10 feet. It measured a whopping 175.3 meters for the European and Canadian readers out there.

George Herman ‘Babe’ Ruth’s 575-foot home run came at Navin Field (later named Tiger Stadium) in Detroit, Michigan on July 18th in a game against the Tigers. Some measurements but Babe Ruth’s home run at 560 feet but most agree it was 575 and the longest home run in MLB history.
