Titanium(III) fluoride (TiF₃) is a inorganic compound with the formula TiF₃. It is a violet solid. It adopts a perovskite-like structure such that each Ti center has octahedral coordination geometry and each fluoride ligand is doubly bridging.

It can be obtained by the reaction of titanium(III) oxide with hydrofluoric acid. This reaction reverses if the TiF₃ is dissolved in water.
