The Runde West Side Bird Sanctuary (Norwegian: Runde vestside fuglefredningsområde) is a bird sanctuary and Ramsar site on the island of Runde in Herøy Municipality in Møre og Romsdal county, Norway. The area was protected in 1981 together with three other bird sanctuaries in order to "take care of rich and interesting bird life and a bird habitat, especially with respect to seabirds," according to the conservation regulations. The four sites have a total area of 2.6 square kilometers (1.0 sq mi).
The sanctuary covers the west side of the bird cliff on Runde, from just south of the Runde Lighthouse all the way to the southwest end of the island, encompassing the Lundeura and Raudenipa viewing points. It spans an area of 85 hectares (210 acres).
In 2013, the area was designated a Ramsar wetland site as one of five subareas of the Runde Ramsar Site (Ramsar reference no. 2164). The other subareas include the Runde North Side Bird Sanctuary, the Hellestien-Blåfjellet-Kløfjellet-Geita Bird Sanctuary, the Goksøyr Mires Nature Reserve (all on the island of Runde), and the Grasøyane Bird Sanctuary in the neighboring municipality of Ulstein.
The island of Runde is well known for its large seabird colonies, including puffins, gannets, kittiwakes, razorbills, and guillemots, which nest on the steep cliffs along the western side of the island.
