GamesRadar is a multi-format video game website featuring previews, reviews, features, videos, cheats, forums and breaking news. It was also formerly known as "CheatPlanet.com". It is owned and operated simultaneously in the UK  and US by Future Publishing (which includes Future US), a worldwide publisher of enthusiast and lifestyle websites and magazines. GamesRadar receives approximately 3.25 million unique visitors per month, and also includes CheatPlanet, which was acquired by Future in 2005.

On September 11, 2007, GamesRadar launched a downloads feature called Fileradar. Fileradar allows users to download mods, hacks and content for games on the PC.

On February 7, 2008, GamesRadar got a complete site makeover.

One of the site's most popular features is their "Top 7" lists, similar to top 10 lists found on many other sites. The PC section of GamesRadar is organized by the gaming magazine PC Gamer. PC Gamer's official U.S. website, PC Gamer Online, formerly redirected to GamesRadar; it now goes to its own site hosting articles from recent issues.

On 14 August 2008 it was announced that the British forums would be closed down and merged with the American side of the site. In response, some of the members of the British forums launched their own forum, named GRcade.
