St. Mary's Church (German: Marienkirche) is a church in Reutlingen, Germany. It was built from 1247–1343 and is one of the most distinct Gothic buildings in Swabia.
Between the 1520s and 1540s the church was a center of the Swabian reformer Matthäus Alber, who spread the teachings of Martin Luther to Reutlingen and surrounding areas. The church was heavily damaged during a fire in 1726. From 1893-1901 it was rebuilt in Neo-Gothic style.
The church has been a National Cultural Landmark since 1988.
