Wii Sports is a 2006 sports simulation video game developed and published by Nintendo for the Wii video game console. The game was released in North America along with the Wii on November 19, 2006, and was released in Japan, Australia, and Europe the following month. It was included as a pack-in game with the console in all territories except Japan, making it the first sports game included with the launch of a Nintendo system since Mario's Tennis for the Virtual Boy in 1995. Wii Sports is available on its own as part of the Nintendo Selects collection of games.

The game is a collection of five sports simulations, designed to demonstrate the motion-sensing capabilities of the Wii Remote. The five sports included are tennis, baseball, bowling, golf and boxing. Players use the Wii Remote to mimic actions performed in real-life sports, such as swinging a tennis racket.[1] The rules for each game are simplified to make them more accessible to new players. The game also features training and fitness modes that monitor players' progress in the sports.

Wii Sports was well received by critics, received a number of awards, and is considered one of the best video games ever made. Selling over 82 million copies by the end of 2017, it is the best selling single-platform game of all time, and fourth best overall. The title also bears the distinction of being the best-selling Nintendo video game of all time. Wii Sports has been featured on television in Wii commercials, news reports, as well as other programming. The game has become a popular means for social gatherings and competitions among players of varying ages. A sequel, Wii Sports Resort, was released in 2009, while a high-definition remake, Wii Sports Club, was released in 2013 for the Wii U.
