Aconitic acid is an organic acid. The conjugate base of aconitic acid, aconitate is a substrate of the citric acid cycle. It is acted upon by aconitase.

Aconitic acid can be synthesized by dehydration of citric acid using sulfuric acid:^[1]

(HO₂CCH₂)₂COH(CO₂H) → HO₂CCH=C(CO₂H)CH₂CO₂H + H₂O

It was first prepared by thermal dehydration.^[2]
