NXT UK was a brand of the American professional wrestling promotion WWE that was introduced in December 2016. Brands are divisions of WWE's roster where wrestlers are assigned to perform on a weekly basis. Wrestlers assigned to NXT UK primarily appeared on the brand's weekly television program, NXT UK, and the brand's periodic livestreaming events. The brand served as a sub-brand of WWE's developmental territory, NXT, with NXT UK wrestlers also occasionally appearing on its show, NXT, as well as NXT's major events. Unlike WWE's other brands, NXT UK was produced exclusively in the United Kingdom and was specifically centered on wrestlers from the country.

In sports, a farm team, farm system, feeder team, feeder club, or nursery club is generally a team or club whose role is to provide experience and training for young players, with an agreement that any successful players can move on to a higher level at a given point, usually in an association with a major-level parent team. This system can be implemented in many ways, both formally and informally. It is not to be confused with a practice squad, which fulfills a similar developmental purpose but the players on the practice squad are members of the parent team.
