Chlorotrifluoromethane, R-13, CFC-13, or Freon 13, is a non-flammable, non-corrosive chlorofluorocarbon (CFC) and also a mixed halomethane. It is used as a refrigerant, however, due to concerns about its ozone-depleting potential, its use has been phased out due to the .

It can be prepared by reacting carbon tetrachloride with hydrogen fluoride in the presence of a catalytic amount of antimony pentachloride:

CCl₄ + 3HF → CClF₃ + 3HCl

This reaction can also produce trichlorofluoromethane (CCl₃F), dichlorodifluoromethane (CCl₂F₂) and tetrafluoromethane (CF₄).
