Kaspar Förster (alsoCaspar Foerster) (baptized 28 February 1616 inDanzig – 2 February 1673 inOliva, near Danzig) was a German singer and composer.

Förster studied music under his father Kaspar (1574-1652) and then underMarco Scacchi inWarsaw. He sang bass and conducted choirs at thePolish court in Warsaw from 1638 to about 1643, then served askapellmeister toFrederik III of Denmark inCopenhagen between 1652 and 1655. In 1655, a war broke out betweenDenmark andSweden, and Förster returned to Danzig, working ascantor at the Marienkirche there. He returned to the employ of Frederik from 1661 to 1667. During this time he visitedVenice several times and played a role in bringing aspects of Italian musical style to northern Europe. He also studied underGiacomo Carissimi in the 1660s. Late in his life he worked briefly inHamburg before returning to his birthplace.

Förster's surviving works are mostly sacredcantatas for three voices, with twoviolins andcontinuo. Some 35 survive, and they often contain very low and difficult bass parts. His other works include twooratorios, sixtrio sonatas, and four secularcantatas.
