Avatar was released in December 2009 and went on to break multiple box office records in various markets. Worldwide, it became the highest-grossing film of all time and the fastest film to gross $1 billion through $2.5 billion, while also achieving the highest grosses in both the 3D and IMAX formats. In its domestic market of the United States and Canada, it set the records for the highest-grossing film and the highest-grossing second through seventh weekends, as well as becoming the fastest film to gross $500 million through $750 million. Elsewhere, it became the highest-grossing film of all time in over 30 markets including China, Hong Kong, Romania, South Korea, Taiwan, and the United Kingdom.

Box office analysts identified several factors contributing to the film's success. Among these were the relative lack of competition owing to the release date, a marketing strategy that emphasized the novelty of the cinematic experience which led viewers to watch it in the theater rather than at home, positive word of mouth and repeat viewings increasing the film's staying power in theaters, an ability to attract audiences across the globe, and higher ticket prices from 3D and IMAX showings. Many of the records set by the film are listed below. Pre-Avatar records and new records surpassing Avatar are presented where available and applicable. All grosses are given in unadjusted US dollars, except where noted otherwise.

Worldwide Avatar set the worldwide record for the highest gross of all time, surpassing the previous record by more than 50%, and grossed $2 billion in less time than it had taken the previous fastest-grossing film to gross half as much.
