The club opened on 5 May 1985. Its name is reference to
Groucho Marx saying he did not want to be a member of any club that would have him. The club was owned by
Graphite Capital from 2006 to 2015, when it was sold to a group of investors led by Isfield Investments and Alcuin Capital Partners. In 2022, the Groucho Club was purchased through
Manuela and Iwan Wirth's Art Farm, which owns a group of boutique hotels and restaurants, for £40 million. In March 2024, the club announced that it would be opening its inaugural branch outside of London at Bretton Hall near Wakefield in Yorkshire. In November 2024, the club's license was suspended by Westminster City Council as a result of a criminal investigation. During the closure, CEO Elli Jafari stepped down after 10 months in the role. Simon Cooke, former Managing Director of Ronnie Scott's Club, has taken over as interim managing director. The reopening introduced updated guest sign-in procedures, requiring digital registration through the Groucho app to enhance safety and security. ==Members==
