The Schrödinger's Cat Trilogy is a trilogy of novels by American writer Robert Anton Wilson consisting of Schrödinger's Cat: The Universe Next Door (1979), Schrödinger's Cat II: The Trick Top Hat (1980), and Schrödinger's Cat III: The Homing Pigeons (1981), each illustrating a different interpretation of quantum physics. They were collected into an omnibus edition in 1988.

Robert Anton Wilson was an American author, futurist, psychologist, and self-described agnostic mystic. Recognized within Discordianism as an Episkopos, pope and saint, Wilson helped publicize Discordianism through his writings and interviews. In 1999 he described his work as an "attempt to break down conditioned associations, to look at the world in a new way, with many models recognized as models or maps, and no one model elevated to the truth". Wilson's goal was "to try to get people into a state of generalized agnosticism, not agnosticism about God alone but agnosticism about everything."
