Methylcyclohexane (cyclohexylmethane) is an organic compound with the molecular formula is CH₃C₆H₁₁. Classified as saturated hydrocarbon, it is a colourless liquid with a faint odor.

Methylcyclohexane is used as a solvent. It is mainly converted in naphtha reformers to toluene. A special use is in PF-1 priming fluid in cruise missiles to aid engine start-up when they run on special nonvolatile jet fuel like JP-10. Methylcyclohexane is also used in some correction fluids (such as White-Out) as a solvent.
