The 1955 major league baseball season began on April 11, 1955. The regular season ended on September 25, with the Brooklyn Dodgers and New York Yankees as the regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the 52nd World Series on September 28 and ended with Game 7 on October 4. In the sixth iteration of this Subway Series World Series matchup, The Dodgers defeated the Yankees, four games to three, capturing their first championship in franchise history. This was the first World Series between the two teams to see the Dodgers win over the Yankees. Going into the season, the defending World Series champions were the New York Giants from the 1954 season.

The 22nd Major League Baseball All-Star Game was held on July 12 at Milwaukee County Stadium in Milwaukee, Wisconsin, home of the Milwaukee Braves. The National League won, 6–5.

In a continuation of the relocation trend that began in 1953, a team moved for the third consecutive year.

The Athletics moved from Philadelphia to Kansas City, Missouri, leaving Philadelphia as a one-team city.

On April 14, the New York Yankees became the 13th team to break baseball’s color line when they called up Elston Howard.
