Fluoromethane, also called methyl fluoride, is a hydrofluorocarbon, a chemical made only of the elements carbon, hydrogen, and fluorine. It is a molecule of methane where one one hydrogen atom has been replaced by a fluorine atom. It has the chemical formula CH3F.

Fluoromethane was the first organofluorine compound found by chemists.
