Léon-Eugène Méhédin (21 February 1828, L'Aigle – 4 March 1905, Bonsecours) was a French archaeologist, architect and photographer. Méhédin's was a fervent Bonapartist and his career was greatly facilitated when he erected two triumphal arches in L'Aigle in 1851 to celebrate Napoléon III's French coup of that year. In 1855, he designed Civitavecchia's train station and went on a mission of photo reconnaissance to the Crimean War with Jean-Charles Langlois.
