The 1957 New York Giants season involved the team finishing in sixth place in the National League with a 69–85 record, 26 games behind the NL and World Champion Milwaukee Braves. It was the team's 75th and final season in New York City before its relocation to San Francisco, California for the following season. The last game at their stadium, the Polo Grounds, was played on September 29 against the Pittsburgh Pirates.

Relocation to San Francisco

While seeking a new stadium to replace the crumbling Polo Grounds, the Giants began to contemplate a move from New York, initially considering Metropolitan Stadium in Minneapolis–St. Paul, which was home to their top farm team, the Minneapolis Millers. Under the rules of the time, the Giants' ownership of the Millers gave them priority rights to a major league team in the area. At this time, the Giants were approached by San Francisco mayor George Christopher. Despite objections from shareholders such as Joan Whitney Payson (who later owned the expansion Mets), majority owner Horace Stoneham entered into negotiations with San Francisco officials around the same time that Dodgers' owner Walter O'Malley was courting the city of Los Angeles. O'Malley had been told that the Dodgers would not be allowed to move to Los Angeles unless a second team moved to California as well. He pushed Stoneham toward relocation. In the summer of 1957, both the New York Giants and the Brooklyn Dodgers announced their moves to California, and the golden age of baseball in the New York area ended.
