The 1911 New York Giants season was a season in American baseball. It involved the Giants winning their first of three consecutive National League pennants. They were beaten by the Philadelphia Athletics in the World Series.

Led by manager John McGraw, the Giants won the NL by 7.5 games. On the offensive side, they finished second in total runs scored. On the defensive side, they allowed the fewest. Hall of Famer Christy Mathewson led the league in ERA, and Rube Marquard had the most strikeouts.

Taken together with the 1912 and 1913 pennant winners, this team is considered one of the greatest of all-time.
