Art Gallery of Ballarat, Regional art museum in Ballarat, Australia

Art Gallery of Ballarat is a museum in a Renaissance Revival building that houses more than 11,000 artworks from the 1700s to today. The collection includes paintings, sculptures, and decorative objects arranged throughout multiple galleries.

The museum was founded in 1884 and moved to its current building in 1890, where it remains today. It later came under council management and grew to become a major art institution in the region.

The gallery's name changed from Ballarat Fine Art Gallery to Art Gallery of Ballarat in 2008, the year it became free-entry. Its collection, built since 1884, focuses on the history of Australian art, including Eugene von Guerard's commissioned painting Old Ballarat as it was in the summer of 1853-54 (1884), which depicts the city's development.

The gallery stands at 40 Lydiard Street North, in Ballarat's central grid, and entry has been free since the 2008 renaming. The main display rooms are on the upper floor, reached by a large stone stairway with Art Nouveau ceiling decoration. Temporary exhibitions run alongside the permanent rooms, and the shop and cafe were relocated during the 2009 renovation.

The gallery's best-known possession, the Eureka Flag, has been on long-term loan to the Eureka Centre since leaving these rooms, so visitors here will not see it. The building itself is the oldest purpose-built art gallery in Australia, designed by Tappin, Gilbert and Dennehy and opened in 1890.
