Methylcyclopentane is an organic compound with the chemical formula CH₃C₅H₉. It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum. It usually is obtained as a mixture with cyclohexane. It is mainly converted in naphthene reformers to benzene.^[2] The C₆ core of methylcyclopentane is not perfectly planar and can pucker to alleviate stress in its structure.^[3]

The conversion of methylcyclopentane to benzene is a classic aromatization reaction, specifically a dehydroisomerization. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum.
