The Clarence Club, formerly known as the Literary Union Club, was a gentlemen's club founded in 1826, as a socially exclusive dining society that met in Conduit Street, Mayfair, by the poet Thomas Campbell, with the objective of the facilitation of social connections between those with an interest in the arts, philosophy, finance, trade, business, and science. Most of its members were English, but, originally, it included a significant core of members of Scottish descent. It is notable for its prohibition, then radical, of the extension of membership to any member of the press.
