Kolka Lighthouse (Latvian: Kolkas bāka) is a lighthouse located in Irbe Strait, 5.2 kilometres (3.2 mi) off the Latvian coast on a specially created artificial island.

The lighthouse guides ships around the dangerous Cape Kolka, at the eastern entrance to the Irbe Strait from the Gulf of Rīga.

[2] A pair of range lights was built on the point of the cape in 1818 to guide ships around the offshore shoals.

A temporary wooden lighthouse was lit offshore in 1875, well before completion of the permanent iron tower, which was built in Saint Petersburg[3] and delivered by sea in parts.

The island was built in the winters 1873-1875 by bringing big stones from the coast via ice road.
