The Seaside Aquarium is Oregon's oldest privately owned aquarium, proudly operating since 1937 at 200 North Promenade along the scenic Oregon coast in Seaside. This beloved coastal attraction invites visitors to interact with a variety of Pacific Northwest marine species, including harbor seals that guests can feed, as well as sea stars, anemones, rockfish, and other local ocean life in touch tanks and interactive exhibits. The aquarium is deeply committed to conservation, contributing to marine mammal stranding response, sea turtle rescue operations, and the Haystack Rock Awareness Program. Dog-friendly and open year-round, the Seaside Aquarium offers an accessible and educational oceanside experience that connects people of all ages to the wonders of Pacific Northwest marine life.
