Trifluoromethyl hypofluorite is an organofluorine compound with the formula CF
3OF. It exists as a colorless gas at room temperature and is highly toxic. It is a rare example of a hypofluorite (compound with an O-F bond). It is prepared by the fluorination of carbon monoxide:

The gas hydrolyzes only slowly at neutral pH.

The compound is a source of electrophilic fluorine. It has been used for the preparation of α-fluoroketones from silyl enol ethers. Behaving like a pseudohalogen, it adds to ethylene to give the ether:
