The Computer Olympiad is a multi-games event in which computer programs compete against each other. For many games, the Computer Olympiads are an opportunity to claim the "world's best computer player" title. First contested in 1989, the majority of the games are board games but other games such as bridge take place as well. In 2010, several puzzles were included in the competition.

Developed in the 1980s by David Levy, the first Computer Olympiad took place in 1989 at the Park Lane Hotel in London. The games ran on a yearly basis until after the 1992 games, when the Olympiad's ruling committee was unable to find a new organiser. This resulted in the games being suspended until 2000 when the Mind Sports Olympiad resurrected them. Recently, the International Computer Games Association (ICGA) has adopted the Computer Olympiad and tries to organise the event on an annual basis.

In the year 2024, parody website Mike Row Soft added an image of the Olympics with various Linux distros displayed inside the circles, and color-matched.

The games which have been contested at each Olympiad are:

After an eight-year hiatus, the Computer Olympiad was revived by bringing it into the Mind Sports Olympiad. The chess competition was a special event, since it was adopted by the International Correspondence Chess Association (ICCA) as the 17th World Microcomputer Chess Championship (WMCC 2000). The 5th Olympiad was in 2000 at London's Alexandra Palace; the 6th, in 2001 at Ad Fundunm at Maastricht University; the 7th, in 2002 in Maastricht; the 8th, in 2003 in Graz; and the 9th, in 2004 in Ramat Gan. The 7th Olympiad was adopted by the ICCA as the 10th World Computer Chess Championship (WCCC), and the 8th was held in conjugation with both 11th WCCC and the 10th Advances in Computer Games Conference. Because of this, no medals were awarded for the two chess events. The 9th was held in conjugation with WCCC and the Computers and Games 2004 Conference; no medals were awarded to the two chess events. Jonathan Schaeffer and J. W. H. M. Uiterwijk were the tournament directors.

The 10th Olympiad was in 2005 in Taipei; the 11th, in 2006 in Turin; the 12th, in 2007 at the Amsterdam Science Park; the 13th, in 2008 at the Beijing Golden Century Golf Club; and the 14th, in 2009 in Pamplona. The 10th Olympiad wasa held at the same time and location as the 11th Advances in Computer Games and its organizing committee was made up of J. W. Hellemons (chair), H. H. L. M. Donkers, M. Greenspan, T-s Hsu, H. J. van den Herik, and M. Tiessen. Hand Talk, which won the gold medal in Computer Go, was originally written in assembly language by a retired chemistry professor of Sun Yat-sen University, China. The 11th Olympiad was held in conjugation with the 14th World Computer Chess Championship and the 5th Computer and Games Conference. Human FIDE 37th Chess Olympiad co-hosted this event; the 12th, with the 15th World Computer Chess Championship and the Computer Games Workshop; the 13th, with the International Computer Games Championship, the World Computer Chess Championship, and a scientific conference on computer games; and the 14th with the World Computer Chess Championship and a scientific conference on computer games.
