Karl Keller (German, 16 October 1784, Dessau – 19 July 1855, Schaffhausen) was a German flautist and composer. His name is sometimes rendered as Charles in English-speaking countries. Keller's works are mostly oriented towards the usage of flutes in a concert setting as well as a paucal number in guitar exists. Despite this, he was described in the 19th edition of the British music magazine, The Monthly Musical Record, as "[c]omposer of several pieces".
