Titanium(III) fluoride is the inorganic compound with the formula TiF₃. A violet, paramagnetic solid, it is one of two titanium fluorides, the other being titanium tetrafluoride.{{cite book |doi=10.1002/0471238961.2009200113051908.a01 |chapter=Fluorine Compounds, Inorganic, Titanium |title=Kirk-Othmer Encyclopedia of Chemical Technology |year=2000 |last1=Meshri |first1=Dayal T. |isbn=978-0-471-48494-3 }} It adopts a defect perovskite-like structure such that each Ti center has octahedral coordination geometry, and each fluoride ligand is doubly bridging.{{cite journal|journal=Acta Crystallogr.|year=1998|volume=B54|pages=578–584|doi=10.1107/S0108768198001207|title=Pressure-Induced Octahedron Strain in VF₃-Type Compounds|author1=H.

Titanium(III) fluoride can be prepared by dissolution of titanium metal in hydrogen fluoride. In air, it slowly oxidizes to titanium(IV).
