The Judas Pair is a crime novel by Jonathan Gash.

The story was first published in 1977 and won a John Creasey Award.

Antiques dealer Lovejoy is commissioned to hunt down what he considers to be a mythical object, the Judas pair, the supposed thirteenth pair of duelling pistols, an 18th-century flintlock[2] made by the famous London gunmaker Durs Egg.

Lovejoy solves the mystery by drawing from his comprehensive knowledge of the antique world, poring on the backgrounds of materials so that past and present deceit and criminality are revealed.
