Kamnik is a town in northern Slovenia. It is the central settlement of the Municipality of Kamnik. It encompasses a large part of the Kamnik Alps and the surrounding area. The town of Kamnik has three castles as well as many examples of historical architecture.

The name Kamnik was first mentioned in the 11th century. The first time it was mentioned as a town was in 1229, when it was an important trading post on the road between Ljubljana and Celje. This makes the town one of the oldest in Slovenia. In the Middle Ages, Kamnik had its own mint and some aristocratic families among its residents. The town was among the most influential centers of power for the Bavarian counts of Andechs in the region of Carniola at the time. The only remnant of the Bavarian nobility are the two ruined castles which are both strategically built on high ground near the town center. The Franciscan monastery built in the town itself is a testament to its importance. The building is well preserved and has undergone extensive renovation in recent years.

Most of the old town center is built in an Austro-Hungarian style. Most of the facades have been renovated in recent years but the process is still ongoing.

Kamnik is the site of a mass grave from the period immediately after the Second World War. The Cuzak Meadow Mass Grave is located in the southeast part of the town, in a grassy area encircled by a road on the premises of the Svit factory. The grave contains the remains of several hundred soldiers and civilians, mostly Croats but also some Serbs, that were murdered on 11 May 1945.
