Big 9 Conference

This is about a high school athletic conference in Minnesota. For the more well-known college sports conference that played under that name from 1899 to 1917 and from 1946 to 1949, see Big Ten Conference.

The Big 9 Conference was organized on April 28, 1928 at a meeting in Owatonna, Minnesota. The schools that associated themselves together "to promote athletic interests and good fellowship among the schools" were Albert Lea, Austin, Faribault, Owatonna, Mankato, Red Wing, Rochester, and Winona. It was then called the Big Eight.
