Roselawn is a census-designated place (CDP) in Newton and Jasper counties in the U.S. state of Indiana. The population was 4,131 at the 2010 census.
Roselawn is known within northwestern Indiana for the two nudist resorts which operate in this town: the Ponderosa Sun Club and Sun Aura. Sun Aura resort was previously known as Naked City, but closed in 1986 after its operator, Dick Drost, encountered significant legal troubles. The resort continued to operate under several different owners and was known as Sunspot resort prior to becoming Sun Aura. The clubs are long-standing fixtures of the community, dating to the 1930s.
