The social nudity movement includes a large range of variants including "naturism", "nudism", "Freikörperkultur (FKK)", the "free beach movement" as well as generalized "public lands/public nudity" advocacy.

Naturism, or nudism, is a cultural and political movement practising, advocating, and defending personal and social nudity, most but not all of which takes place on private property.
The term may also refer to a lifestyle based on personal, family, or social nudism. It may be practiced individually, within a family, socially, or in public.
