'''Ovalene''' is a [[polycyclic aromatic hydrocarbon]] with the formula C<sub>32</sub>H<sub>14</sub>, which consists of ten peri-fused six-membered rings. It is very similar to [[coronene]].
Ovalene is a reddish-orange compound. It is sparingly soluble in solvents such as [[benzene]], [[toluene]], and [[dichloromethane]]. Its solutions have a green [[fluorescence]] under [[UV light]].
Ovalene has been shown to form in deep-sea [[hydrothermal vent]] areas and in the [[hydrocracking]] process of petroleum refining.
