The Art Gallery of Hamilton is an art museum located in Hamilton, Ontario, Canada. The museum occupies a 7,000 square metres building on King Street West in downtown Hamilton, designed by Trevor P. Garwood-Jones. The museum relocated to the building in 1977, with renovations by Bruce Kuwabara later undertaken in 2005.
The museum was established as the Municipal Gallery of Hamilton in January 1914, and was opened to the public in June 1914, at a Hamilton Public Library building on Main Street West. The museum continued to operate from that location until 1953, when the museum relocated to a new building in the neighbourhood of Westdale. In 1977, the museum moved to its present King Street West location. The museum building was renovated with designs by Bruce Kuwabara from 2003 to 2005.
The Art Gallery of Hamilton's permanent collection has over 10,000 works by artists from Canada, and around the world. In addition to exhibiting works from its collection, the museum has also organized, and hosted a number of travelling exhibitions.
