1,2-Benzisoxazole is an aromatic organic compound with a molecular formula C₇H₅NO containing a benzene-fused isoxazole ring structure. The compound itself has no common applications; however, functionalized benzisoxazoles and benzisoxazoyls have a variety of uses, including pharmaceutical drugs such as some antipsychotics (including risperidone, paliperidone, ocaperidone, and iloperidone) and the anticonvulsant zonisamide.

Its aromaticity makes it relatively stable; however, it is only weakly basic.
