Delta College is a two-year community college located southwest of Bay City, Michigan, United States. Delta College's district had its beginning in 1955 with Saginaw, Midland, and Bay counties making up the district. In 1957, the voters of the tri-counties approved the construction of the college, and it opened for classes in 1961. Delta College replaced Bay City Junior College, established in 1922, because the junior college could no longer support the growing enrollment.
