Isobenzofuran is a heterocyclic compound consisting of fused benzene and furan rings. It is isomeric with benzofuran.

Isobenzofuran is highly reactive and rapidly polymerizes; however, it has been identified[1] and prepared by thermolysis of suitable precursors and trapped at low temperature.[2]

Though isobenzofuran itself is not stable, it is the parent of related stable compounds with more complex structures.[3]
