Georg Caspar Schürmann (1672 (or early 1673), in Idensen bei Neustadt am Rübenberge – 25 February 1751, in Wolfenbüttel) was a German Baroque composer.
Schürmann studied music, including voice, in his native Lower Saxony.
In 1707 Schürmann officially succeeded Reinhard Keiser as Cammer-Componist (court composer).
He served the court of Brunswick, with but a few brief interruptions, for 54 years until he died at the age of 79.
His music was characterized by harmonic richness, careful contrapuntal elaboration, flexible handling of form and theatrically effective delineation of characters.
