Karl Friedrich Curschmann (June 21, 1805 – August 24, 1841) was a German song composer and singer.

In 1824, having been a law student in Berlin and Göttingen, he started to devote his life to music.

At Kassel in 1828 he wrote his first opera Abdul und Errinieh oder Toten.

After 1837 he lived with Rose Behrend, daughter of a Danzig businessman and herself a singer, before they married and engaged heavily in the musical life of Berlin.

Curschmann wrote 83 songs, many to the poems of Goethe, Schiller, Heine and Rückert.
