Tetrafluoromethane, also known as carbon tetrafluoride, freon-14, refrigerant 14, and R14, is a carbon fluoride. It has the molecular formula CF₄. It melts at -184 °C and boils at -128 °C. It can be considered either a haloalkane or an inorganic compound.

Tetrafluoromethane is a gas that contributes to the greenhouse effect. The C-F bond in tetrafluromethane is very strong, therefore it lasts a long time in the atmosphere and is a very powerful greenhouse gas. According to the Kyoto Protocol, this gas should only be released as a last resort.
