Gallium(III) fluoride (GaF₃) is a chemical compound. It is a white solid that melts under pressure above 1000 °C but sublimes around 950 °C. It has the FeF₃ structure where the gallium atoms are 6-coordinate.{{Greenwood&Earnshaw}} GaF₃ can be prepared by reacting F₂ or HF with Ga₂O₃ or by thermal decomposition of (NH₄)₃GaF₆.Anthony John Downs, (1993), Chemistry of Aluminium, Gallium, Indium, and Thallium, Springer, {{ISBN|978-0-7514-0103-5}} GaF₃ is virtually insoluble in water. Solutions of GaF₃ in HF can be evaporated to form the trihydrate, GaF₃·3H₂O, which on heating gives a hydrated form of GaF₂(OH). Gallium(III) fluoride reacts with mineral acids to form hydrofluoric acid.
