Art Gallery of Mississauga, Contemporary art museum in downtown Mississauga, Canada.

Art Gallery of Mississauga is a contemporary art museum in downtown Mississauga housed in a modern building with expansive windows. Natural light flows throughout the exhibition spaces during the day, creating bright rooms for viewing.

The Art Gallery of Mississauga is a public, not-for-profit gallery located in the Mississauga Civic Centre on Celebration Square. In 2011 it commissioned Lord Cultural Resources to plan a facility expansion; that study found it was the smallest public art gallery in Canada's sixth-largest city. In 2013 artist Camille Turner became its first Artist in Residence, and in 2014 it rebranded with a design by Toronto's The White Room, a finalist in the Graphis 2015 competition.

The gallery displays works from local and Canadian artists that reflect current directions in contemporary art. Visitors can observe how today's artists express their ideas through visual forms.

The gallery sits inside the Mississauga Civic Centre on Celebration Square, across from Square One Mall, and is closed Mondays. Admission is free, with guided exhibition tours, workshops for adult learners and programmes for schools and community groups. Because the entrance is tucked inside the Civic Centre, visitors often walk past it; look for the gallery within the building rather than a separate facade.

The gallery's XIT-RM Project Space, opened in 2012 with RBC Foundation sponsorship, shows six emerging regional artists each year, each with its own opening and a published catalogue essay. It has hosted shows such as Lise Beaudry's Sur la glace, winner of the 2012 BMW Exhibition Prize.
