Jean Baptiste Louis George Seroux D'Agincourt (1730 - 1814) was a French archaeologist and historian.

Born at Beauvais, he belonged to a good family, and in his youth served as an officer in a regiment of cavalry. Finding it necessary to quit the army in order to take charge of his younger brothers who had been left orphans, he was appointed a farmer-general by Louis XV. In 1777 he visited England, Germany and Holland; and in the following year he travelled through Italy, with the view of exploring thoroughly the remains of ancient art. He afterwards settled at Rome, and devoted himself to preparing the results of his researches for publication.

He died in 1814, leaving the work, which was being issued in parts, unfinished; but it was carried on by M. Gence , and published complete under the title L'Histoire de lart par les monuments, depuis sa decadence au quairime sicle jusqud son renouvellement au seizime (6 vols. fol. with 325 plates, Paris, 1823). In the year of his death D'Agincourt published in Paris a Recueil de fragments de sculpture antique, en terre cuite.
