SNK Corporation (株式会社SNK Kabushiki-gaisha Esu Enu Kee) is a Japanese video game hardware and software company, successor to the Original SNK Corporation (Shin Nihon Kikaku) and current owner of the SNK video game brand and Neo Geo video game platform. The Shin Nihon Kikaku Corporation was founded in 1978 by Eikichi Kawasaki. Initially called Shin Nihon Kikaku (新日本企画, lit. "New Japan Project"), the name was informally shortened to SNK Corporation in 1981 before becoming the company's official name in 1986.

SNK is most notable as creator of the Neo Geo family of arcade, home, and handheld game consoles, beginning in 1990. The Neo Geo line was halted in 2001, when financial troubles forced SNK Corporation to close in 2001. Anticipating the end of the company, Kawasaki founded Playmore Corporation in 2001 and Playmore acquired all of the intellectual property of the former SNK Corporation. In 2003, Playmore Corporation was renamed to SNK Playmore Corporation. In 2016, SNK dropped the "Playmore" name from its logo and reintroduced its old slogan, "The Future Is Now", officially changing its corporate name back to SNK.

Traditionally, SNK operated primarily as a video game developer, publisher, and hardware manufacturer, focusing on arcade games but also working on console and PC games. In 2004, the company started manufacturing pachislot machines, which the company leaned heavily into before withdrawing from the market in 2015. In 2009, the company also entered an active wave of mobile game development. Classic SNK franchises like Metal Slug, Samurai Shodown and The King of Fighters feature heavily in its recent offerings.
