These aren't real museums, but I there are these:

Flash Museum - a museum dedicated to the Flash's exploits in gratitude from the people of Keystone city.

JSA Museum, a headquarters that doubles as a museum for the Justice Society of America, built from the house where the former Sandman once lived.

Hawkman (one of them, anyway) worked at the Stonechat Museum in St. Roch as a curator.
