Julien-David Le Roy or Leroy (French pronunciation: [ʒyljɛ̃ david ləʁwa]; 6 May 1724 in Paris – 28 January 1803 in Paris) was an 18th-century French architect and archaeologist, who engaged in a rivalry with Britons James Stuart and Nicholas Revett over who would publish the first professional description of the Acropolis of Athens since an early 1682 work by Antoine Desgodetz. Le Roy succeeded in printing his Ruins of the Most Beautiful Monuments of Greece four years ahead of Stuart and Revett.
