Valac is a demon described in the goetic grimoires the Lesser Key of Solomon (in some versions as Ualac or Valak and in Thomas Rudd's variant as Valu), Johann Weyer's Pseudomonarchia Daemonum (as Volac), the Liber Officium Spirituum (as Coolor or Doolas), and in the Munich Manual of Demonic Magic (as Volach) as an angelically winged boy riding a two-headed dragon, attributed with the power of finding treasures and opening gateways.
The Lesser Key, the Munich Manual, Rudd, and Weyer further agree in ranking Valac as a president and attributing him with the power to locate, summon, and control serpents. The Officium Spirituum similarly attributes Doolas with the power to give the summoner command of serpents as well as "household spirits," but it ranks Cooler and Doolas as princes instead of presidents.
Valac is listed sixty-second in the Lesser Key (even by Rudd) and the forty-ninth by Weyer, with either version claiming he leads thirty legions of demons (though some manuscripts say thirty-eight). The Munich Manual describes Volach as controlling twenty-seven legions of spirits. The Officium Spirituum (depending on the manuscript) ranks Coolor as either twenty-first (with no note of how many spirits he commands) or (in the copy found in the Folger Shakespeare Library) twenty-second and commanding thirteen legions of spirits. All extant and complete versions of the Officium Spirituum list Doolas as twenty-fifth demon, commanding twenty legions of spirits.
A manuscript titled Fasciculus Rerum Geomanticarum lists him as Volach.
In popular culture

- The 2016 horror film The Conjuring 2 has "Valak" as the main antagonist, taking in the form of a demonic nun. However, the character bears no resemblance with mythology besides the name.
