Cyclopentene is a chemical compound with the formula C5H8.[1] It is a colorless liquid with a petrol-like odor. It is one of the cycloalkenes.

Cyclopentene is produced industrially in large amounts. It is used as a monomer for synthesis of plastics, and in a number of chemical syntheses.

It can be obtained from vinylcyclopropane in the vinylcyclopropane-cyclopentene rearrangement.
