Georg Christoph Biller was a German choral conductor. He conducted the Thomanerchor as the sixteenth Thomaskantor since Johann Sebastian Bach from 1992 to 2015. He was also a baritone, an academic teacher, and a composer. Active as Thomaskantor after the German reunification, Biller returned the Thomanerchor to its original focus on church music. He was instrumental in the new buildings for the choir's boarding school, the Forum Thomanum, and in the celebration of its 800th anniversary in 2012.

The Thomanerchor is a boys' choir in Leipzig, Germany. The choir was founded in 1212. The choir comprises about 90 boys from 9 to 18 years of age. The members, called Thomaner, reside in a boarding school, the Thomasalumnat and attend the St. Thomas School, Leipzig, a Gymnasium school with a linguistic profile and a focus on musical education. The younger members attend the primary school Grundschule Forum Thomanum or Anna-Magdalena-Bach-Schule. Johann Sebastian Bach served as Thomaskantor, director of the choir and church music in Leipzig, from 1723 to 1750.
