Altena Castle (German: Burg Altena) is a medieval hill castle in the town of Altena in North Rhine-Westphalia. Built on a spur of Klusenberg hill, the castle lies near the Lenne in the Märkischer Kreis.

The castle was erected by the early Counts of Berg in the early 12th century.^[1] Eventually, the House of Berg abandoned Altena and moved their residence to Hamm.
