List of players who have converted from one football code to another

There are many footballers who have converted from one football code to another at a professional or representative level. In some cases, the player may also return to the original code, so the traffic is not merely one way.

In some countries, such as the United Kingdom, United States, Ireland and Australia, where multiple codes are popular, and the practice of switching codes is relatively common, such players are known as code converts or code hoppers. In Australia, star code converts can have a substantial impact on the games. For instance, Dally Messenger's defection from rugby union to rugby league was considered a pivotal moment in the establishment of the latter over other codes in Australia.

Globalisation is increasing the opportunities for players to transfer to different countries and to different professional sports, including the forms of football.
