Caledonian Thebans Rugby Football Club is Scotland's leading inclusive rugby club, with teams playing both rugby union and touch rugby.

Established in 2002, the Thebans were based at Edinburgh's Murrayfield Stadium and have over 100 registered players. The club supports its players and supporters – whether gay or straight, experienced or new to the game – to enjoy rugby at a competitive level.

Through twice-weekly coaching sessions and regular matches against both mainstream and inclusive clubs (whose members are often drawn from the LGBT community), the Thebans aim to develop confident players and encourage participation in rugby union and touch rugby from groups who may have been under-represented in the sport.

The Thebans was formed as a club primarily for gay and bisexual men who wanted to play rugby, but may have lacked the confidence to join a mainstream team. The club came to life on 18 May 2002 when Colm Cunningham, a gay man from Northern Ireland, put up a poster in the Laughing Duck – a now defunct Edinburgh gay bar.

In 2006 the club became more performance orientated. The club's playing squad now also includes a diverse mix of gay, bisexual and straight players.

In February 2016, the club played its first competitive fixture against Glasgow Alphas RUFC, the second inclusive team to be formed in Scotland.

In 2023 the Thebans established a women's+ team, the Caledonian Thebans Hydra – reflecting the Thebans' aim of promoting inclusion and encouraging participation in the game.

In 2025 the Thebans established a touch team, The Caledonian Thebans Midas.
