Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF₂. The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride.^[1]

The compound has a T-shaped geometry.^[1] It is a weak Lewis acid, adducing acetonitrile and forming the trifluoroxenate(IV) ion in hydrogen fluoride. With strong fluoride acceptors, the latter generates the hydroxydifluoroxenonium(IV) ion (HOXeF+2), suggesting a certain Brønsted basicity as well.^[2]

Although stable at low temperatures, it rapidly decomposes upon warming, either by losing the oxygen atom or by disproportionating into xenon difluoride and xenon dioxydifluoride:^[1]
