Piter De Vries is a fictional character from the Dune universe created by Frank Herbert. He is primarily featured in the 1965 novel Dune, but also appears in the Prelude to Dune prequel trilogy (1999–2001) by Brian Herbert and Kevin J. Anderson.

De Vries is portrayed by Brad Dourif in David Lynch's 1984 film Dune, and by Jan Unger in the 2000 Dune miniseries.

In the service of the ruthless Baron Vladimir Harkonnen, De Vries is a Mentat — a human specially trained to perform mental functions rivaling computers, which are forbidden universe-wide. In addition, De Vries has been "twisted" (made into an amoral sadist) by his Tleilaxu creators.

De Vries is so loyal to Harkonnen that he continues to serve the Baron with great enthusiasm even though his Mentat abilities and great intelligence confirm his suspicions that his master plans to eventually kill him. As he says in Dune:

But you see, Baron, I know as a Mentat when you will send the executioner. You will hold back just so long as I am useful. To move sooner would be wasteful and I'm yet of much use.

De Vries is described in the novel Dune (though not portrayed on screen) as being addicted to the drug melange, which has colored both the sclera and irises of his eyes a characteristic deep blue.

In Dune, it is established that De Vries had pioneered a type of toxin called "residual poison" which remains in the body for years and requires an antidote to be administered regularly. One such fatal poison is secretly administered by the Harkonnens to Thufir Hawat, the Mentat of House Atreides, in order to keep Hawat's allegiance as the only provider of the antidote (in the 1984 movie version, it is shown that Hawat has to milk a gruesome captive cat for the antidote every day).
