The Little Ten Conference is a former high school athletic conference in Wisconsin, formed in 1925 and reorganizing into the Wisconsin Little Ten Conference in 1970.

The Little Ten Conference was founded in 1925 by ten medium- to smaller-sized schools in south central Wisconsin: Beaver Dam, Berlin, Columbus, Hartford Union, Horicon, Mayville, Portage, Ripon, Watertown and Waupun.^[1] The conference went through a few membership changes during its first few seasons, starting with the loss of Portage to the South Central Conference in 1926^[2][3] and Watertown to the Southern Six in 1928.^[4][5] The conference added West Bend in 1929^[6][7] and Oconomowoc in 1930 to bring conference membership back up to ten.^[8] Membership would remain consistent until 1959, when Arrowhead joined from the Southeastern Wisconsin Conference and Watertown rejoined from the Braveland Conference.^[9]

With conference membership increasing to twelve, the Little Ten subdivided into Northern and Southern Divisions for the 1959-60 school year:^[10]

In 1965, Arrowhead left to join the Southeastern Badger Conference,^[11][12] bringing conference membership to eleven. By the late 1960s, increasing gaps in enrollment between the smaller schools in the Northern Little Ten and the larger schools in the Southern Little Ten were creating problems with competitive balance, and the schools in the Southern Little Ten began looking to secede from the conference.^[13][14][15] The conference officially subdivided into two separate conferences in 1966^[16] and both conferences completely disbanded in 1970. The five Southern Little Ten members (six with the split of West Bend into East and West)^[17] joined with Waupun, who had the highest enrollment in the Northern Little Ten,^[18] to form the Wisconsin Little Ten Conference.^[19] The five schools in the Northern Little Ten disbanded to find other conferences with schools more similar in enrollment size.^[20][21]
