The Wausau Lumberjacks (occasionally known as the Timberjacks) were a minor league baseball team based in Wausau, Wisconsin that existed on-and-off from 1905 to 1957. The Wausau franchise then became the Wausau Timbers before relocating to become today's Kane County Cougars. The Lumberjacks played in the Wisconsin State League (1905–1907, 1946–1949), Wisconsin–Illinois League (1908, 1912–1914), Minnesota–Wisconsin League (1909–1911) and Northern League (1936–1939, 1956–1957).
