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.[1]

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