Pierre Paul Leroy-Beaulieu (French pronunciation: [pjɛʁ pɔl ləʁwa boljø]; 9 December 1843 in Saumur – 9 December 1916 in Paris) was a French economist, brother of Henri Jean Baptiste Anatole Leroy-Beaulieu, born at Saumur, Maine-et-Loire on 9 December 1843, and educated in Paris at the Lycée Condorcet and the École de Droit. He afterwards studied at Bonn and Berlin, and on his return to Paris began to write for Le Temps, Revue nationale and Revue contemporaine.
In 1867, he won a prize offered by the Academy of Moral and Political Sciences with an essay entitled L'Influence de état moral et intellectuel des populations ouvrières sur le taux des salaires. In 1870 he gained three prizes for essays on La Colonisation chez les peuples modernes, L'Administration en France et en Angleterre, and L'Impôt foncier et ses conséquences économiques. In 1872, Leroy-Beaulieu became professor of finance at the newly founded École Libre des Sciences Politiques, and in 1880 he succeeded his father-in-law, Michel Chevalier, in the chair of political economy in the Collège de France. In his last years, he was co-president of the Société d'économie politique from 1911 to 1916.
