Xenon tetrafluoride, XeF4, is one of the few chemical compounds involving a noble gas. It was the first discovered binary compound containing a noble gas. It is formed by the reaction of Xe and F2 in the ratio of 1 mol Xe to 2 mol F2. The process is exothermic, releasing 251 kJ per mol of Xe. It occurs as colorless crystals.

It sublimes at 115.7 °C (240.26 °F).

Xenon fluorides are all exergonic, and quite stable at normal temperatures. They do react readily with water, even pulling water from air, so they must be kept in anhydrous conditions.
