The Saginaw Valley High School Association (commonly referred to as the Saginaw Valley League) is a high school sports league formed in 1904 within the Michigan High School Athletic Association (MHSAA), located in the Bay, Genesee, Isabella, Lapeer, Midland, and Saginaw, Counties in Michigan area.
It was formed in the fall of 1904 with five teams: Bay City Eastern (Bay City Central), Bay City Western (Bay City Handy), Saginaw Eastern (Saginaw High), Arthur Hill, and Flint High (Flint Central).
In August 2012, the final four teams of the Big Nine Conference, Carman-Ainsworth, Davison, Flint Powers Catholic and Flushing, joined the league in its South Division. With the Flint Metro League losing Lapeer East and Lapeer West, Flushing and Carman-Ainsworth applied to join that league with Flushing's membership approved starting in the 2014-15 year.
The Saginaw Valley League currently has 14 member schools.
