Chromium hexafluoride or chromium(VI) fluoride is a hypothetical chemical compound between chromium and fluorine with the chemical formula {{chem2|CrF6|auto=6}}. It was previously thought to be an unstable yellow solid decomposing at −100 °C,{{cite journal|doi=10.1021/ic00026a002|title=Is chromium hexafluoride octahedral?

Steven|journal=Inorganic Chemistry|volume=30|issue=26|pages=4873}} but this has been shown to be a misidentification of chromium pentafluoride, CrF₅.{{cite journal |last1=Riedel |first1=Sebastian |last2=Kaupp |first2=Martin |year=2009 |title=The highest oxidation states of the transition metal elements |journal=Coordination Chemistry Reviews |volume=253 |issue=5–6 |doi=10.1016/j.ccr.2008.07.014 |pages=606–624}}
