The Allentown Chiefs were a minor league baseball team. They played in the Class A Eastern League, and started the 1957 season in Syracuse, New York. The team was purchased by the Boston Red Sox and was moved to Allentown, Pennsylvania, mid-season on July 13, 1957, and finished the season playing at Breadon Field in Whitehall Township, just north of Allentown.

The 1957 team was not affiliated with any major league team, however, the Chiefs were a longtime affiliate of the Detroit Tigers prior to the 1957 season. After finishing the season in Allentown, the team was re-designated as the Allentown Red Sox, with Boston moving their Eastern League Class A team from Albany, New York, to Allentown for the 1958 season.

A new Detroit-affiliated team in Lancaster, Pennsylvania, began operations for the 1958 Eastern League season.
