Seattle Aquarium

The Seattle Aquarium opened in 1977. The Aquarium was owned and operated by the City of Seattle Department of Parks and Recreation until 2010, when the nonprofit Seattle Aquarium Society assumed its management under a long-term operating agreement with the City. Today, the Seattle Aquarium is the ninth largest aquarium in the U.S. by attendance. Since our opening, we’ve hosted over 28 million visitors and provided marine conservation education to over two million school children. We’re proud to be accredited by the Association of Zoos and Aquariums (AZA), and are also a proud member of the World Association of Zoos and Aquariums.
