The Trondheim Art Museum (Norwegian: Trondheim Kunstmuseum, previously Trøndelag Kunstgalleri) is an art museum located in Trondheim in Sør-Trøndelag county, Norway. The museum shows temporary exhibitions of international and regional art in dialogue with works from the museum's collection. The museum possesses Norway's third largest public art collection with an emphasis on art since 1850. The permanent collection contains iconic works such as Harald Sohlberg's Natt (Røros church) (1904), Georg Jacobsen's Haren (1922), and Peder Balke's Nordkapp (1870s).
The Trondheim Art Museum has two venues, TKM Bispegata (Bispegata 7 b) situated near the Nidaros Cathedral and TKM Gråmølna at Nedre Elvehavn. The main building in Bispegata 7 b was built in 1930 according to plans by architect Peter Daniel Hofflund. The Trondheim Art Museum was established in 1997, as a means to maintain the museum collection. The building has two floors with rooms of varied sizes and light. The building was refurbished in 2012, when artificial lights were installed to provide more stable temperature and lighting. Much of the interior was restored to its original state from 1930.
