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.
From 1969–1979, the Conference splint into a Saginaw Valley East and a Saginaw Valley West Conference. Many Conference Realignments happened during this time.
Flint Northwestern was included in the Saginaw Valley League up until 2001, as it became an Independent in 2002.
Mount Pleasant High School entered the Valley for the first time in 2005 after the 2002–2003 season being the last of the Mid-Michigan Athletic Conference-A.
Saginaw Heritage entered the Conference in 1994 after a consolidation of Eisenhower High School and MacArthur High School although it was in the White-Pine Conference since its creation (1988) to 1992–1993.
Pontiac Central High School left the Conference after the 1994 season for the Oakland II Conference, now the Oakland-Blue Conference.
Neither Bay City T.L. Handy, Bay City Western, nor Bay City Central are included in the 1978 football results, because none of the Bay City schools had football teams that year.
After the 1979–1980 season Bay City T.L. Handy left the Saginaw Valley Conference to join the White-Pine Conference in 1988, and ultimately closed its doors after the 1989–1990 school year, only to be later opened as T.L. Handy Middle School.
