Sterigmatocystin is a polyketide mycotoxin produced by certain species of Aspergillus. The toxin is naturally found in some cheeses.

Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins as it is the penultimate precursor of aflatoxins B1 and G1. It contains a xanthone nucleus attached to a bifuran structure. Sterigmatocystin is mainly produced by the fungi Aspergillus nidulans and A. versicolor.
