St. Thomas Church is a Lutheran church in Leipzig, Germany. It is associated with several well-known composers such as Richard Wagner and Felix Mendelssohn Bartholdy, but mostly with Johann Sebastian Bach who worked here as a Kapellmeister from 1723 until his death in 1750. Today, the church also holds his remains. Martin Luther preached here in 1539.
Although rebuilt over the centuries and damaged by Allied incendiary bombs in 1943, the church today mainly retains the character of a late-Gothic hall church. The Thomanerchor, the choir of the Thomaskirche, likely founded in 1212, remains a well-known boys' choir.
