GURPS Mixed Doubles is a collection of characters intended for use with the GURPS role-playing game accessory Supers.

Each superhero or supervillain character entry in the book is paired with another one, often with an enemy or a rival, but sometimes with a partner, a relative and, in two cases, lovers.

Shane L. Hensley reviewed GURPS Mixed Doubles in White Wolf #35 (March/April, 1993), rating it a 3 out of 5 and stated that "Overall, the characters are original and well fleshed out.

Each entry has a detailed history, ways to fit it into a campaign, a discussion of his or her abilities, and battle tactics.
