The Gay Mafia or Velvet Mafia is a term for a supposed group of powerful gay people, usually men, who use their influence to further their own goals and those of other gays, while excluding or actively working against non-gay people.[1] It has been described as a conspiracy theory similar to that which supposed that Jews were a "a diabolical group that was consolidating power everywhere from the banking industry to Hollywood."[2] "Gay Mafia" and "Velvet Mafia" are also used humourously by gay people themselves. The term was widely used in the 1980s and 1990s, and could often be seen in the pages of the New York Post.
