Østerlars Church is a historical building located just north of the village of Østerlars, 5 kilometres (3.1 mi) south of Gudhjem on the Danish island of Bornholm, Denmark. It is the largest and, possibly, the oldest of the island's four round churches. Built around 1160, it was dedicated to St. Lawrence. It consists of an apse, an oval chancel, a large round nave and has three storeys.
