Wikipedia doesn’t have a history of Oceanside yet. The photos, dates and memories neighbors add here are how it gets written.
Oceanside is a census-designated place (CDP) and unincorporated community in Tillamook County, Oregon, United States. As of the 2020 census, Oceanside had a population of 366. Oregon Route 131's northern terminus is in the community, which is just north of Netarts. Symons State Park is in Oceanside, while Three Arch Rocks National Wildlife Refuge lies just offshore.
Its first post office opened in 1924. Its population held steady between the last two censuses: 361 in 2010, 366 in 2020.
