Swayne Field was a minor league baseball park in Toledo, Ohio. It was the home of the Toledo Mud Hens from July 3, 1909, until the club disbanded after the 1955 season. It was also home to a short-lived entry in the South-Michigan League in 1914. The park was named for Noah H. Swayne, Jr., the son of U.S. Supreme Court Justice Noah Haynes Swayne, who donated the land for the ballpark. The double-decker ballpark replaced Armory Park. The main stand was built of steel and concrete, one of the first minor league ballparks not made primarily of wood.
