Provided is a method for producing trans-1-chloro-3,3,3-trifluoropropane efficiently from an intermediate product having a low reactivity. Provided is a method for producing trans-1-chloro-3,3,3-trifluoropropane characterized by reacting a halogenated hydrocarbon compound having three carbon atoms represented by general formula (1) in a gas phase with hydrogen fluoride in the presence of chlorine. General formula (1): C3HXClYFZ (In the formula: X is 2 or 3; and when X=2, Y is an integer from 1 to 4, Z is an integer from 0 to 3, and Y+Z=4; and when X=3, Y is an integer from 1-5, Z is an integer from 0-4, Y+Z=5. General formula (1) indicates a halogenated hydrocarbon compound having 3 carbon atoms and excluding trans-1-chloro-3,3,3-trifluoropropane.).
