Altena ( pronunciation ) is a town in the district of Märkischer Kreis, North Rhine-Westphalia, Germany. The town's castle is the origin for the later Dukes of Berg. Altena is situated on the Lenne river valley, in the northern stretches of the Sauerland.

Altena Castle was built in the early 12th century, as a stronghold of the older Counts of Berg. A short time later a village was founded beneath the hill, with the castle alongside the river Lenne. After the distribution of the Berg family estates in 1161, Altena became the centre of the County of Altena. The first Count of Altena became Eberhard I, Count of Berg-Altena. In 1180, after the death of the first count, the county was divided between the two oldest sons: Arnold of Altena and Friedrich of Altena. The third son, Adolf of Altena, became Archbishop of Cologne. Arnold was provided with on half of the Castle and County of Altena, the Castle Hövel and some estates as fiefdoms of the Archbishops of Cologne and bailiwicks of the Abbey Essen. Near the Village and Castle of Hövel, he built the Castle and town of Nienbrügge (Novus Ponte) on the Lippe riverbanks. His family branch renamed themselves after selling their half of Altena to the Archbishop of Cologne as de Nienbrügge or de Novus Ponte, their new principle residence about forty kilometers to the north. The heir of Arnold was Friedrich de Novus Ponte (Nienbrügge) who changed his title to Isenberg after his new castle in Hattingen. He was sentenced to death as head of the conspiration to murder Engelbert I. Archbishop of Cologne, Chancellor of the Holy Roman Empire, Duke of Westphalia and Count of Berg - a close relative - in 1226. The Archbishop was ambushed and slain on his way from his City of Soest to City of Cologne by Friedrich and his men near Gevelsberg in a hollow way. Both had a dispute over the bailiwicks of Essen Abbey.
