The 2012 St. Louis Cardinals season was the 131st season for the St. Louis Cardinals, a Major League Baseball franchise in St. Louis, Missouri. It was the 121st season for the Cardinals in the National League and their 7th at Busch Stadium III.

The Cardinals made their 25th trip to the postseason in 2012 after taking the NL Wild Card title by one game over the Atlanta Braves on the last day of the regular season in 2011. They began the 2012 season away against the Miami Marlins on April 4. St. Louis was coming off a 90–72 (.556) season, a second-place finish in the National League Central Division, the aforementioned wild card berth, and their National League-leading 11th World Series championship.

In 2012, they finished with an 88–74 (.543) record and second place in the NL Central. By virtue of coming in second to the Atlanta Braves, they won the second National League Wild Card spot, and then beat the Braves in the NLWC Game. They then played the NL East champion Washington Nationals in the NLDS and beat them in five games to advance to the NLCS against the San Francisco Giants. However, they lost to the Giants in seven games after leading the series 3 games to 1.
