The Prejmer fortified church 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.

The south-eastern Transylvania region in Romania currently has one of the highest numbers of existing fortified churches from the 13th to 16th centuries. It has more than 150 well preserved fortified churches of a great variety of architectural styles.
