The Warrington Wolves are a professional rugby league football club in the town of Warrington, Cheshire in England. They compete in Super League, Europe's top-level rugby league competition. Their colours are primrose (light yellow) and blue, though white has often featured on the home shirt. Warrington have lifted many of the major rugby league trophies, including the Challenge Cup in August, 2009. This was their first major honour since 1974 when they last lifted the Challenge Cup. Their last major cup final appearance prior to this was in 1990 against local rivals Wigan. Warrington is one of the original twenty-two rugby clubs that formed the Northern Rugby Football Union in 1895, making them one of the world's first rugby league teams. In the past the club have been nicknamed "The Wire" or "Wires", in reference to the strength of the wire-pulling industry in Warrington. They previously played at the traditional ground of Wilderspool, but have since moved to the Halliwell Jones Stadium. They are the only club in the history of the sport in England to play every one of their seasons in the top flight.
