The Duluth White Sox were a minor league baseball team based in Duluth, Minnesota, that played from 1903 to 1916, and in 1934. The team played in the Northern League (1903–1905, 1908, 1913–1916, 1934), Northern-Copper Country League (1906–1907), Minnesota–Wisconsin League (1909–1911) and Central International League (1912). The team was known as the "Cardinals" in 1903. When professional baseball returned to Duluth in 1934 after 18 years, the name White Sox was used for one season before the team became the Duluth Dukes.
