The Harlequin Football Club (The Harlequins or Quins for short) is an English rugby union team who will play in the top level of English rugby, the Guinness Premiership, for 2006-07, having secured their return from National Division One at the first opportunity. Their ground in London is traditionally known as The Stoop though it has recently been renamed The Twickenham Stoop. For sponsorship reasons they are known as Harlequins.
In the amateur era many of the players worked in the City of London and the club has retained strong ties to the financial sector. Harlequins Rugby League is a separately owned rugby league team which, from 23 September 2005, shares the same name, ground and wears kit similar to the union club's famous multi-coloured quartered jersey.
