Orehek (pronounced [ɔˈɾeːxək]) is a dispersed settlement below Mount Kojca west of Cerkno in the traditional Littoral region of Slovenia.

[2] In addition to the village center, Orehek contains the hamlets and isolated farmsteads of Gradež, Nemci, Zabrežnica, Mlinar, Abram, and Androjne.

During the Second World War, there was an engagement between Italian forces and the Partisans at Rodne Hill (689 meters or 2,260 feet) southwest of the village.

A fire caused by a short circuit destroyed most of the village on July 18, 1951—at the time, most of the houses still had thatched roofs.

[5] It was built in 1755 and is a Baroque structure with a polygonal chancel walled on three sides, a wider rectangular nave, and a bell tower.
