Niğde Archaeological Museum (Turkish: 'Niğde Arkeoloji Müzesi') is located in the centre of the Turkish provincial capital, Niğde between Dışarı Cami Sokak and Öğretmenler Caddesi. It contains objects found at sites in the surrounding area, including the tell of Köşk Höyük and the Graeco-Roman city of Tyana, both in the nearby town of Kemerhisar.
From the Second World War until 1950, part of the collection of the Istanbul Archaeological Museum was kept in the Akmedrese, the main Quran school in Niğde, on Ak Medrese Caddesi. The building continued to be used as a museum after that. Because that space ceased to be sufficient for the collection, work began on a new museum building in 1971. The Akmedrese was closed in 1977and the new museum was opened to visitors on 12 November 1982. Soon the collection outgrew this building as well and it was accordingly rebuilt and renovated. The re-opening of the present museum occurred in 2001. The museum is or has been active in excavations at Köşk Höyük, Porsuk Hüyük, Kestel, Göllü Dağ, Andaval, Eskigümüş and Kınık Höyük.
The museum's objects are displayed in ix chronologically ordered rooms. Room 1 contains finds from prehistoric times, including Stone Age artefacts like obsidean spearpoints and arrowheads, which fall under the purview of the Obsidian Use Project. They come from Göllü Dağ, Köşk Höyük, Pınarbaşı Gölü, Kaletepe , and other locations and date back to the 12th millennium BC. A large number of pottery objects from the sixth and fifth millennia BC are also displayed, most of which come from the excavations at Köşk Höyük. There is also a reconstruction of a house from this settlement.
