Iron tetrafluoride is a binary inorganic compound with the chemical formula FeF4. It was initially observed in 2003 via mass spectrometry and Fourier-transform infrared spectroscopy. Iron tetrafluoride is assumed to have tetrahedral or square planar structure. It has been calculated to be stable in the gas phase.

Iron tetrafluoride can be prepared by reaction of iron with fluorine in excess neon and argon at 4 K:

Fe + 2F2 → FeF4
