The St. Thomas Church (German: Thomaskirche) is a Lutheran church in Leipzig, Germany, located at the western part of the inner city ring road in Leipzig’s central district. Martin Luther preached in the church in 1539. It is associated with several well-known composers, especially Johann Sebastian Bach, who was its Thomaskantor (music director) from 1723 until his death in 1750. The church holds his remains.
