The present invention provides a method for producing a fluorine-containing haloolefin compound, the method easily inhibiting catalyst deactivation, and the method being capable of inhibiting a decrease in conversion and selectivity in the reaction, even when the reaction is continued for a long period of time. The present invention is a method for producing a fluorine-containing haloolefin compound via a step of fluorinating a C3 halogenated hydrocarbon. The method comprises a step of removing a stabilizer contained in the C3 halogenated hydrocarbon before the fluorination step.
