Fumonisin B4 (or FB4) is a fumonisin mycotoxin produced mainly by the fungi Fusarium proliferatum, Fusarium verticillioides (formerly Fusarium moniliforme). Recently FB4 has been detected in fungi Aspergillus niger and in several Tolypocladium species.

FB4 is similar to fumonisin B2 and fumonisin B3 but it is lacking a hydroxy group located gamma- to the amino substituent while lacking two hydroxy groups compared to fumonisin B1.

Fumonisin B4 was first described in 1991.
