The Davenport Blue Sox was the name given to three minor league baseball teams based in Davenport, Iowa. The first version of the Blue Sox played in the Class B Three-I League from 1913–1916. The second played in the Class D Mississippi Valley League from 1929–1933, and the third version played in the Western League from 1934–1937. From 1936–1937, the team was a minor league affiliate of the Brooklyn Dodgers. The Blue Sox played their home games at Municipal Stadium from 1931–1937 and were the foundation for today's tenant, the Quad Cities River Bandits.

The 1933 club has been rated as the 58th best minor league baseball team of all time.
