The Wenatchee Chiefs were a minor league baseball team in the northwest United States, based in Wenatchee, Washington. Founded in 1937, the team was a part of the Class B Western International League through 1954, although the team did not operate after 1941 and the entire league was suspended during World War II, for the seasons from 1943 to 1945. The Chiefs were one of the seven founding members of the Northwest League in 1955, where they remained until the team suspended operations after the 1965 season, the last before the NWL went to the short-season format.
