A pride flag is any flag that represents a segment or part of the LGBTQ community. Pride in this case refers to the notion of LGBTQ pride. The terms LGBTQ flag and queer flag are often used interchangeably.
The rainbow flag, which represents the entire LGBTQ community, is the most widely used pride flag. As well as the LGBTQ community as a whole, pride flags can represent various sexual orientations, romantic orientations, gender identities, subcultures, and regional purposes. Some pride flags, however, are not exclusively related to LGBTQ matters, such as the flag for leather subculture.
