Deathstalker II, also known as Deathstalker II: Duel of the Titans, is a 1987 Argentine-American fantasy comedy-adventure film directed by Jim Wynorski and a sequel to 1983's Deathstalker. It was written by Neil Ruttenberg (with an extensive uncredited rewrite by Wynorski, Terlesky and R. J. Robertson) and starring John Terlesky, Monique Gabrielle, John LaZar and María Socas. Terlesky replaced Rick Hill, the protagonist from the previous film, in the starring role of Deathstalker. This is the last sword and sorcery movie that Roger Corman produced in Argentina during the 80s.

Owing to its low-cost production and the perceived self-awareness of the movie, Wynorski called the film an "anachronistic comedy of sorts".

In the film, a princess is replaced by her evil clone. She poses as a seer while trying to reclaim her kingdom.
