Phenylpyruvic acid is the organic compound with the formula C₆H₅CH₂C(O)CO₂H. It is a keto acid.

The compound exists in equilibrium with its E- and Z-enol tautomers. It is a product from the oxidative deamination of phenylalanine.

It is prepared by condensation of benzaldehyde and glycine derivatives to give phenylazlactone, which is then hydrolyzed with acid- or base-catalysis. It can also be synthesized from benzyl chloride by double carbonylation.
