The club's football team was established in 1918 and has played in the fourth division Oberliga Hessen since 2000 with the exception of the 2003–04 and 2007–08 seasons played in the Landesliga Hessen-Nord (V). Their best result was a second-place finish in 2013–14.
The origins of the club go back to the 1892 founding of Älterer Turnverein Obervellmar. In 1933, the association was forced to merge with Arbeiter Turn- und Sportverein 1907 Obervellmar under the policies of the Nazi regime which saw to the dissolution of worker's clubs which were considered to be ideologically undesirable. By 1934 the club was known as TuS Obervellmar and was renamed OSC Vellmar in 1976.
OSC plays its home matches at the Sportplatz Heckershäuser Straße which has a capacity of 4,000.
