The Anchorage Museum at Rasmuson Center is a museum located in downtown Anchorage in the U.S. state of Alaska. Beginning as a public-private partnership to celebrate the 100th anniversary of the Alaska purchase, it opened in 1968 with an exhibition of 60 borrowed Alaska paintings and a collection of 2,500 historic and ethnographic objects loaned from the local historical society, and the museum has been enlarged several times since. Its official name is now Anchorage Museum at Rasmuson Center.
