Langlois is an unincorporated community and census-designated place in Curry County, Oregon, United States, on the Oregon Coast established in 1881. As of the 2010 census it had a population of 177. Langlois was once famous for its blue cheese, until the cheese factory burned down in the 1950s. It was never rebuilt. Langlois was named for William Langlois, an early Oregon pioneer. As phonetically spelled in the 1860 Federal Census, Port Oxford Precint [sic], page 110, the name was pronounced "Langless", as it is most commonly pronounced today by residents.
