Namco Limited (株式会社ナムコ Kabushiki gaisha Namuko) is a corporate brand name in use by two Japanese companies, and a former developer and publisher of video games for arcades and home platforms. The name is currently in use by Namco USA, a subsidiary of Bandai Namco Holdings, as well as a brand name for video games on modern platforms. The company was originally headquartered in Ōta, Tokyo. Two international divisions were established - Namco America in Santa Clara, California, and Shanghai Namco in Hong Kong.

Namco was founded on June 1, 1955 by Masaya Nakamura as Nakamura Seisakusho, which produced rocking horses and coin-operated mechanical arcade games for Japanese department stores. Nakamura found success in these ventures, renaming the company in 1959 to Nakamura Amusement Machine Manufacturing Company - shorted to Namco in 1971. After establishing Namco Enterprises Asia in China, Nakamura acquired the struggling Japanese division of Atari from Nolan Bushnell, giving Nakamura the rights to distribute Atari games in Japan. This was a huge success for the company, and would influence them to create their own video games.

Namco merged its operations with Bandai on September 25, 2005, forming Bandai Namco Holdings. The video game operations continued under the original company and its Namco name until March 31, 2006, when it was renamed to Namco Bandai Games. The Namco brand was spun-off into a separate company of the same name, which handled the operations of amusement parks and arcade centers internationally. This new company would be renamed to Bandai Namco Amusement in 2018. Namco Bandai Games, now known as Bandai Namco Entertainment, is one of Japan's largest video game developers and one of the world's most-profitable game companies.

Namco has produced several successful video game franchises, including Pac-Man, Galaxian, Tekken, Soulcalibur, Dig Dug, Xevious, Ridge Racer and Ace Combat. It also operated Japanese game centers and amusement parks, alongside production of toys, films and electronics.
