Tasmanian Museum and Art Gallery, Heritage museum complex in Hobart, Australia

The Tasmanian Museum and Art Gallery is a cultural complex in Hobart housed within multiple historic buildings, including the 1810 Commissariat Store and the 1902 Customs House. Its collections focus on Tasmania's natural environment, Antarctic exploration history, and colonial heritage.

The Royal Society of Tasmania founded this institution in 1846 as the first such institution created by a Royal Society outside England. Since 1952 it has unified natural science specimens, historical artifacts, and contemporary art exhibitions under single management.

The museum presents the history of Tasmania's Aboriginal peoples and their long relationship with the island through its collections and displays. Visitors can see how these communities shaped and understood their environment over generations.

The museum occupies a full city block between Macquarie and Davey Streets, with entrances from both; the 1810 Commissariat Store and the 1902 Customs House are part of the complex. It reopened on 15 March 2013 after a four-month closure for redevelopment. Three external sites—a herbarium, a storage and research facility, and the Moonah Workshop—are not part of the central Hobart campus.

The museum's site absorbed the whole city block over time, taking in the 1810 Commissariat Store and the 1902 Customs House on Davey Street. Its founding Royal Society of Tasmania, established in 1843, is the oldest royal society outside England. The museum also runs a herbarium, a storage and research facility, and the Moonah Workshop.
