The Bastard Prince is a fantasy novel by American-born author Katherine Kurtz. It was first published by Del Rey Books in 1994. It was the twelfth of Kurtz' Deryni novels to be published, and the third book in her fourth Deryni trilogy, The Heirs of Saint Camber.

The next Deryni novel to be published, King Kelson's Bride, was a direct sequel to the Histories of King Kelson trilogy, but the internal literary chronology of the series was later continued in In the King's Service, the first book of the Childe Morgan trilogy.
