Vioxanthin is a mycotoxin that was first isolated from the pathogenic fungus Trichophyton violaceum and characterized in 1966. It is a pigment with a brownish-yellow color. It has since been found to be a constituent of a variety of other fungi including those in the genus Penicillium and Aspergillus. The detection of vioxanthin in food products has been used as evidence of contamination with these fungi.

A laboratory synthesis of vioxanthin has been reported.
