Patricia Oren Kearney Cadigan (born September 10, 1953) is a British-American science fiction author, whose work is most often identified with the cyberpunk movement.

At the same time, she also worked for fantasy writer Tom Reamy at his Nickelodeon Graphics Arts Service studio, where she daily typset various jobs.

In the late 1970s and early 1980s, she also edited the small press fantasy and science fiction magazines Chacal and later Shayol with her second husband, Arnie Fenner.

Cadigan's first novel, Mindplayers, introduces what becomes the common theme to all her works: her stories blur the line between reality and perception by making the human mind a real, explorable place.

While her stories include many of the gritty, unvarnished characteristics of the cyberpunk genre, she further specializes in this exploration of the speculative relationship between technology and the perceptions of the human mind.
