Actinium oxyfluoride is an inorganic compound, with the chemical formula AcOF. It is radioactive. It crystallises in a calcium fluoride structure.^[3] It can be obtained by reacting actinium fluoride with ammonia and water:^[4]

AcF₃ + 2 NH₃ + H₂O → AcOF + 2 NH₄F^[α]

The reaction proceeds completely at 1200 °C, and unreacted AcF₃ will remain at lower temperatures.^[5]
