The Yale University Art Gallery (YUAG) is the oldest university art museum in the Western Hemisphere. It houses a major comprehensive collection of art in several interconnected buildings on the campus of Yale University in New Haven, Connecticut. Although it embraces all cultures and periods, the gallery emphasizes early Italian Renaissance painting, African sculpture, and modern art.

The gallery was founded in 1832 when patriot artist John Trumbull donated over 100 paintings of the American Revolution to Yale College and designed the original picture gallery. A new building, designed by Yale University architect Egerton Swartwout, was completed in 1928.
