CSK Corporation (株式会社CSK), whose abbreviation has varied in meaning over the years (though originally stood for Computer Service Kabushiki-Kaisha), was a Japanese business services conglomerate. It was founded by Isao Okawa in 1968.

Throughout its run, CSK were involved in numerous fields related to technology, but first took an interest in video games in late 1981, when it started publishing products for Japanese home computers. The following year, it established a subsidiary, CSK Software Products (CSKソフトウェアプロダクツ) to handle this side of the business, partnering with Toei to release games under the "Filcom" brand. At this time, CSK was not developing games in-house, instead out-sourcing projects to various Japanese studios.

In 1984 CSK purchased the Japanese arm of Sega from Gulf+Western, where it would remain a subsidiary of the company until 2004. CSK later began operating its own middleware/software development division, CSK Research Institute (better known as CRI).

In 1995, they established one of Sega's North American divisions called SegaSoft, and in the late 1990s operated GD-NET, a publishing partnership between several game developers (ESP, Quintet, possibly Sting, possibly Game Arts, possibly Treasure, etc.).

In 2011, they merged with Sumisho Computer Systems, with Sumisho taking full control. The merged company continues to operate as SCSK.
