The 1991 Cincinnati Reds season was the 122nd season for the franchise in Major League Baseball, and their 22nd and 21st full season at Riverfront Stadium. The Reds attempted to defend their World Series championship from 1990, but the team would finish with a losing mark, regressing 17 games from the season before. Their winning percentage (.457) set a new record for worst among defending World Series champions, besting the previous mark set by the Chicago White Sox in 1918. This would be a record for seven years.
