Pong is a first generation video game released originally as a coin-operated arcade game by Atari Inc. on November 29, 1972. Pong is based on the sport of table tennis (or "ping pong"), and named after the sound generated by the circuitry when the ball is hit.

The word Pong is a registered trademark of Atari Interactive, while the term "pong" is used to describe the genre of "bat and ball" video games.

Contrary to popular belief, Pong was not the world's first video arcade game (Computer Space, by Nutting Associates, was released in 1971).

However, Pong was the first video game to achieve widespread popularity in both the arcade and home console markets, and it is credited with launching the initial boom in the video game industry.
