Qix (クイックス, Kuikkusu) (pronounced "kicks") is an arcade game developed by Taito America Corporation and released in October 1981. The objective of Qix is to fence off, or claim, a supermajority of the playfield. At the start of each level, the playing field is a large, empty rectangle, containing the "Qix"—a stick-like entity that performs graceful but unpredictable motions within the confines of the rectangle.

Qix was ported to the contemporary Atari 5200 (1982), Atari 8-bit family (1983), and Commodore 64 (1983), then was brought to a wide variety of systems in the late 1980s and early 1990s: MS-DOS (1989), Amiga (1989), another version for the C64 (1989), Apple IIgs (1990), Game Boy (1990), Nintendo Entertainment System (1991), and Atari Lynx (1991).
