Georg Christoph Biller (1955–2022) was a German choral conductor and baritone from Leipzig who began his musical career as a member of the Thomanerchor, studied church music and choral conducting, and later served as Thomaskantor. He specialised in Lutheran sacred music and traditional choral practices, directing liturgical and concert repertoire, commissioning and promoting contemporary compositions alongside historic works during his tenure from 1992 to 2015.
