Coenzyme Q (CoQ /ˌkoʊkjuː/), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. The human body mainly produces the form known as coenzyme Q₁₀ (CoQ₁₀, ubidecarenone), but other forms exist. CoQ is used by and found in many organisms, including animals and bacteria. As a result, it can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.

CoQ plays a role in mitochondrial oxidative phosphorylation, aiding in the production of adenosine triphosphate (ATP), which is involved in energy transfer within cells. The structure of CoQ₁₀ consists of a benzoquinone moiety and an isoprenoid side chain, with the "10" referring to the number of isoprenyl chemical subunits in its tail.

Although a ubiquitous molecule in human tissues, CoQ₁₀ is not a dietary nutrient and does not have a recommended intake level, and its use as a supplement is not approved in the United States for any health or anti-disease effect.
