Georg Michael Telemann (20 April 1748 – 4 March 1831) was a German composer and theologian.
After the death of his father in 1755, he moved to Hamburg, where he was taken in and raised by his then 74-year-old grandfather Georg Philipp Telemann.
On the death of his grandfather in 1767, the 19 year old Georg Michael composed Trauer-Ode auf das betrübte Absterben meines Großvaters Herrn Georg Philipp Telemann, des Hamburgischen Musik-Chor-Direktors.
He also filled his grandfather's post as Cantor at the Johanneum and director of music in Hamburg's churches until March 1768, when Carl Philipp Emanuel Bach was appointed.
In 1812, he published a collection of Chorale settings for organ entitled Sammlung alter und neuer Choral-Melodien and a year later took the position of organist at the cathedral.
