The Houston LGBTQ+ Political Caucus (also officially known as the HLGBTQPC) is the South's oldest civil rights organization dedicated solely to the advancement of gay, lesbian, bisexual and transgender rights. It was founded in 1975, and is the largest LGBTQ political organization in the city of Houston and Harris County. It is known locally simply as "The Caucus." The Caucus is nonpartisan and endorses candidates on the basis of their support for LGBTQ rights, regardless of political party or candidate's sexual orientation.
