The Clowns Gallery-Museum is a museum of clowning. Established in 1959, the collection contains costumes and props from famous clowns, as well as a reference library, and is home to the Clown Egg Register.

The collection is split between the museum's two sites, the Holy Trinity Church, Dalston, and Wookey Hole, Somerset, England. The museum was established in 1959 in Dalston and the collection was split into a venue in Wookey Hole in 2007. The Dalston museum is situated in what was the vestry of the Holy Trinity Church. It was threatened with closure in 2014 but remained in place. The Wookey Hole museum is run by Gerry Cottle, vice president of Clowns International.

The Clown Egg Register is an archive of painted ceramic and hen's eggs that serve as a record of individual clowns' personal make-up designs. The clown egg tradition began in 1946, when Stan Bult, a chemist, and founder of Clowns International, took to drawing the faces of club members and famous clowns onto chicken eggs. The egg gallery was created to forestall the possibility of accidental or intentional plagiarism: an unofficial rule prohibits any two clowns from sharing a single face paint design, with eggs providing a suitably head-shaped mannequin. Real eggs were originally used but were later replaced with ceramic eggs. The gallery is open on the first Friday of each month.
