The Waterloo Hawks were a National Basketball League and National Basketball Association team based in Waterloo, Iowa. The Hawks remain the only sports franchise ever based in Iowa from any of the current Big Four Leagues. (The Keokuk Westerns of the National Association played one year of baseball in 1875; however, this league is not a direct ancestor of any current league, and there is debate as to whether or not to count the league as a major league.)
