The 1927 St. Louis Cardinals season was the team's 46th season in St. Louis, Missouri, and its 36th season in the National League. The Cardinals went 92–61 during the season and finished second in the National League.

Offseason

In a deal that shocked the baseball world, the Cardinals traded long-time star Rogers Hornsby on December 20, 1926, to the New York Giants for Frankie Frisch and Jimmy Ring. The deal was held up because Hornsby, as part of his contract as the manager of the Cardinals (he was a player-manager at the time), owned several shares of stock in the Cardinals. Cardinals owner Sam Breadon offered Hornsby a sum for the stock considerably lower than what Hornsby demanded for it, and neither would budge. Eventually, the other owners of the National League made up the difference, and the trade went through.
