An alternative lifestyle is a lifestyle perceived to be outside the norm for a given culture. The phrase "alternative lifestyle" is often used pejoratively. Description of a related set of activities as alternative is a defining aspect of certain subcultures.

A subculture is a group of people within a cultural society that differentiates itself from the conservative and standard values to which it belongs, often maintaining some of its founding principles. Subcultures develop their own norms and values regarding cultural, political, and sexual matters. Subcultures are part of society while keeping their specific characteristics intact. Examples of subcultures include BDSM, hippies, hipsters, goths, steampunks, bikers, punks, skinheads, gopnik, hip-hoppers, metalheads, cosplayers, otaku, otherkin, furries, and more. The concept of subcultures was developed in sociology and cultural studies. Subcultures differ from countercultures.
