Isoindoline is a heterocyclic organic compound with the molecular formula C₈H₉N. The parent compound has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. The compound's structure is similar to indoline except that the nitrogen atom is in the 2 position instead of the 1 position of the five-membered ring. Isoindoline itself is not commonly encountered, but several derivatives are found in nature and some synthetic derivatives are commercially valuable drugs, e.g. lenalidomide and pazinaclone.

The drug lenalidomide contains the substructure isoindoline (red)
