|Full name||Olympischer-Sport-Club Bremerhaven von 1972 e. V.|
The club was founded in 1972 as Olympischer Sport-Club Bremerhaven in a merger of various local football clubs including ATS Bremerhaven, which has roots going back to 1859, Polizei Sportverein, TuS Bremerhaven 93, and the Judo-Klub. They are the largest sports club in the city, claiming some 4500 members, but football is not their primary focus. Their minor league side currently competes at the tier V level after a decade spent in tiers II and III, from the mid-70s through to the mid-80s.
OSC can make a strong claim to being the successor to TuS Bremerhaven 93, which was officially disbanded in 1974. While many members of TuS 93 joined OSC, others continued to field a separate football team until 1977. In 1991, the football players left OSC en masse to form FC Bremerhaven, leaving OSC with just a rump side. The TuS 93 was a quite successful side in northern German football, playing in the Oberliga Nord (I) from 1948 to 1963 and then in the Regionalliga Nord (II) until 1974.
