Fifty home runs in a season is quite the accomplishment. There have been just 51 50-homer seasons in Major League history. The story of 50-homer seasons begins with the Live Ball Era, in 1920, when Babe Ruth hit 54. In fact, nobody other than Ruth hit 50 or more homers until 1930, when Hack Wilson hit 56.

Which team has had the most 50-homer seasons from its players? That would be the Yankees, with 11. They’re the only team to have multiple players with 50 or more homers in a single season, when Roger Maris and Mickey Mantle did it in 1961. The most 50-homer hitters across the Majors in a single season is four, in 2001 and 1998.

Here’s a list of every 50-homer season in Major League history, in reverse chronological order.
