Youth subculture is a youth-based subculture with distinct styles, behaviors, and interests. Youth subcultures offer participants an identity outside of that ascribed by social institutions such as family, work, home and school. Youth subcultures that show a systematic hostility to the dominant culture are sometimes described as countercultures.

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.
