Benzisoxazole is an aromatic organic compound with a molecular formula C₇H₅NO containing a benzene-fused isoxazole ring structure. Benzisoxazole has no household use. It is used primarily in industry and research.

Being a heterocyclic compound, benzisoxazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. It is found within the chemical structures of pharmaceutical drugs such as the antipsychotic risperidone and the anticonvulsant zonisamide.

Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.
