Thymoquinone is a phytochemical compound found in the plant Nigella sativa. It is also found in select cultivated Monarda fistulosa plants, which can be steam distilled to produce an essential oil. Thymoquinone is also a major oxidation product of both thymol and its structural isomer, carvacrol.

It has been classified as a pan-assay interference compound, which binds indiscriminately to many proteins. It is under basic research to further identify its biological properties.
