Chlorotriiodomethane is a tetrahalomethane with the chemical formula . This is a halomethane containing one iodine atom and three chlorine atoms attached to the methane backbone.

Synthesis Chlorination of iodoform with phosphorus pentachloride leads to carbon tetrachloride via a chlorotriiodomethane intermediate.

It can also be obtained by distilling trichloroacetyl chloride and hydrogen iodide at 140 °C, with hexachloroethane as a byproduct. Trichloromethane or carbon tetrachloride can also be reacted with iodine and sodium hydroxide at 0 °C to obtain the compound, but the yield is very low.
