GamesMaster was a British television programme which originally aired on Channel 4 from 1992 to 1998. In 2021, it returned for a new series on YouTube and E4. It was the first UK television programme dedicated to video games.

Dominik Diamond was the host for six of the original seven series while astronomer Sir Patrick Moore featured as the GamesMaster. He was replaced in 2021 with Sir Trevor McDonald. The show's format consists of a mixture of game reviews, small "features", tips and challenges. Challenges form the biggest section of the show and generally consist of "average" players and celebrities, often competing against each other for the coveted Golden Joystick.
