 * [[image:Diethyldixanthogendisulfide.svg|thumb|right|Structure of [[diethyl dixanthogen disulfide]].]]

Dixanthogen disulfides are a class of organosulfur compounds with the formula (ROC(S)S)2. Usually yellow solids, they are the product of the oxidation of xanthate salts. A common derivative is diethyl dixanthogen disulfide. Diisopropyl dixanthogen disulfide is commercially available. They are structurally related to thiuram disulfides.

Uses and reactions
Diethyl dixanthogen disulfide is a component for froth flotations used, inter alia, for the separation of sulfide minerals like pyrrhotite. Diisopropyl dixanthogen disulfide is a reagent in the synthesis of sulfur heterocycles.

Dialkoxy dixanthogen disulfides undergo desulfurization by cyanide to give bis(alkoxythiocarbonyl)sulfides:
 * (ROC(S)S)2 + CN-  ->  (ROC(S))2S  +  SCN-

Dixanthogens are also ectoparasiticides.
