Olhörn Lighthouse (German: Leuchtturm Olhörn, also Leuchtfeuer Olhörn and sometimes Leuchtturm Olderhörn) is a small lighthouse on the German North Sea island of Föhr in Schleswig-Holstein.

The lighthouse is located on the southeastern corner of the island of Föhr, inside the town of Wyk auf Föhr in the Nordfriesland district. It is located on a shallow geestland ridge overlooking the southern beach of Wyk.

It was erected in 1952 to replace a light beacon from 1892. The tower is 8.6 metres (28 ft) tall with a focal height of 10 m above mean high water. It has a near square shape and was built of massive masonry that was encased by reddish brown bricks. On the gallery there is the lantern room made of metal; it is painted white. The automated lighthouse serves as a cross light for navigation in the Norderaue tidal channel between the mainland port of Dagebüll and the islands of Föhr and Amrum. As such it is a sea mark and also a minor daymark.
