The 1957 major league baseball season began on April 15, 1957. The regular season ended on September 29, with the Milwaukee Braves 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 54th World Series on October 2 and ended with Game 7 on October 10. The Braves defeated the Yankees, four games to three, capturing their second championship in franchise history, their first since 1914, and first in Milwaukee. Going into the season, the defending World Series champions were the New York Yankees from the 1956 season.
The 24th Major League Baseball All-Star Game was held on July 9 at Busch Stadium in St. Louis, Missouri, home of the St. Louis Cardinals. The American League won, 6–5.
The National League's Brooklyn Dodgers and New York Giants played their final seasons as New York City-based franchises before their moves to California for the 1958 season, leaving New York City without a National League team until the founding of the expansion New York Mets in 1962.
On April 22, the Philadelphia Phillies became the 14th team in professional baseball to break the color line when they fielded John Kennedy.
