The Clinton LumberKings are a Midwest League Class A minor league baseball team based in Clinton, Iowa, USA, affiliated with the Seattle Mariners.

After beginning play in 1895, Clinton had sporadic teams in various leagues over the next few decades, as the Great Depression, World War I and World War II affected many baseball franchises. However, Clinton joined the Midwest League in 1956 and is now the oldest franchise in the league. The team has had several different major league affiliations: the Brooklyn Dodgers (1937–38), New York Giants (1939–41), Chicago Cubs (1947–49), Pirates (1954–58 and 1966–68), White Sox (1959–65), Pilots/Brewers (1969–70), Tigers (1971–75), Tigers/White Sox co-op (1976), Dodgers (1977–79), Giants (1980–94), Padres (1995–98), Reds (1999–2000), Expos (2001–02), and the Rangers (2003–08). Since 2009, they have been an affiliate of the Mariners.
