A dichlorodifluoroethylene (systematically named dichlorodifluoroethene) is one of three compounds with the chemical formula C
₂Cl
₂F
₂. Dichlorodifluoroethylenes are colourless gases, and are some of the simplest chlorodifluoroalkenes.

The structural isomers are used as intermediates or precursors in the production of other industrial chemicals.
