Queercore (also known as homocore), is a cultural and social movement that began in the mid-1980s as an offshoot of the punk subculture. It is distinguished by its discontent with society in general, and specifically society's disapproval of the LGBTQ community. Queercore expresses itself in a D.I.Y.

As a musical genre, it may be distinguished by lyrics exploring themes of prejudice and dealing with issues such as sexual identity, gender identity and the rights of the individual; more generally, queercore bands offer a critique of society endemic to their position within it, sometimes in a light-hearted way, sometimes seriously. Musically, many queercore bands originated in the punk scene but the industrial music culture has been influential as well. Queercore groups encompass many genres such as hardcore punk, electropunk, indie rock, power pop, No Wave, noise, experimental, industrial and others.
