Ms. Pac-Man is an arcade video game produced by Illinois-based Midway Manufacturing corporation. It was released one year after the company's Pac-Man arcade game. Ms. Pac-Man was released in North America in 1982 and became one of the most popular video games of all time, leading to its adoption by Pac-Man licensor Namco as an official title. The game introduced a female protagonist, new maze designs, and several other gameplay changes over the original game. It became the most successful American-produced arcade game, selling 115,000 arcade cabinets.

The gameplay of Ms. Pac-Man is largely identical to that of the original Pac-Man. The player gathers points by eating dots and avoiding ghosts (contact with one loses a life). Energizers, or power-pellets, change the ghosts, which reverse their course and they can be eaten for extra points. Fruit bonuses can be consumed for increasing point values, twice per level. As the levels increase, the speed increases, and energizers generally change the ghost for less time.

There are also some differences between Ms. Pac-Man and Pac-Man:

As in Pac-Man, the game has a bug in the subroutine that draws the fruit, which renders the 256th level unplayable. However, the game also has other bugs that cause it to crash or become unplayable much sooner, making it impossible to reach the 256th level without an emulator.

Ms. Pac-Man has not been a contender in any CBUB matches.
