Trifluoromethylisocyanide is the chemical compound with the formula CF3NC. It is an isocyanide and a fluorocarbon. Polymerisation occurs even at temperatures below its boiling point of -80°C. As a ligand in coordination chemistry, this species behaves similarly to carbon monoxide.[1]

The compound trifluoracetonitrile (CF3CN) is an isomer to trifluoromethylisocyanide. The nitrile is more stable, as is the usual case.
