Guy's, Kings and St. Thomas' Rugby Football Club ("GKT") is the name given to the modern amalgam of three formerly distinct hospital rugby clubs each with a long history, having all been founded in the nineteenth century. The teams from Guy's Hospital and St Thomas' Hospital were the first to merge following the union of their respective Medical Departments. When King's College Hospital also merged in 1999 the King's College Hospital Rugby Football Club opted to remain separate and in so doing became an open rugby club that no longer represented the Hospital Medic's. GKT is notable for having been part of the twenty-one founding members of the Rugby Football Union (the Guy's team), and across its joint history has produced a large number of international players.
