Hooker is one of the positions in a rugby league football team. Usually wearing jersey or shirt number 9, the hooker is one of the team's forwards. During scrums the hooker plays in the front row, and the position's name comes from their role of 'hooking' or 'raking' the ball back with the foot. For this reason the hooker is sometimes referred to in Australia as the rake. Hookers have a great deal of contact with the ball, as they usually play the role of acting halfback or dummy half, picking the ball up from the play-the-ball that follows a tackle. Hookers therefore have much responsibility in that they then decide what to do with the ball, whether that be to pass it, run with it, or occasionally to kick it. Therefore, together with the two halves and fullback, hooker is one of the four key positions that make up what is sometimes called a team's 'spine'. A trend of halves converting into hookers followed the introduction of the 10 metre rule, and many players have switched between these positions in their careers such as Geoff Toovey, Andrew Johns, Craig Gower and Peter Wallace.

Rugby league football, commonly known as rugby league in English-speaking countries and rugby XIII in non-Anglophone Europe and South America, and referred to colloquially as rugby, football, footy or league in its heartlands, is a full-contact sport played by two teams of thirteen players on a rectangular field measuring 68 m (74 yd) wide and 112–122 m (122–133 yd) long with H-shaped posts at both ends. It is one of the two major codes of rugby football, the other being rugby union. It originated in 1895 in Huddersfield, Yorkshire, England, as the result of a split from the Rugby Football Union (RFU) over the issue of payments to players. The rules of the game governed by the new Northern Rugby Football Union progressively changed from those of the RFU with the specific aim of producing a faster and more entertaining game to appeal to spectators, on whose income the new organisation and its members depended.
