The Prejmer fortified church (Romanian: Biserica fortificată din Prejmer; German: Kirchenburg von Tartlau) is a Lutheran fortified church in Prejmer (Tartlau), Brașov County, in the Transylvania region of Romania and the ethnographic area of the Burzenland. The church was founded by the Germanic Teutonic Knights, and then was eventually taken over by the Transylvanian Saxon community. Initially Roman Catholic, it became Lutheran following the Reformation. Together with the surrounding village, the church forms part of the villages with fortified churches in Transylvania UNESCO World Heritage Site.
