BSC 1899 Offenbach is a German sports club from Offenbach am Main, Hesse. The club is active in football, gymnastics, children's gymnastics, rugby, volleyball, tennis and sports for the over 65s.

The club was founded in 1899 as Offenbacher FC 1899 as the city's first club. In 1901, some players split from the club to found Offenbacher FC Kickers. The club joined the South German Football Association and took part in the qualification for the final round in 1902/03, but was immediately defeated by Viktoria Aschaffenburg.

Later the club took the name BSC 1899 Offenbach. On August 31, 1922, the club merged with Offenbacher FV 02 and thus took the name SpVgg 1899 Offenbach. After two seasons, the fusion club was relegated from the highest class. On April 9, 1927, the merger was undone and both clubs went their separate ways again.
