The Rockford Peaches were a team in the All-American Girls Professional Baseball League playing out of Rockford, Illinois for the entire existence of the league from 1943 to 1954. Although the 1992 movie A League of Their Own features the Rockford Peaches, all of the characters playing on the team were fictional. The team, however, did lose the league championship in 1943 as depicted in the film.
