Maurice Hauriou (17 August 1856 – 12 March 1929) was a French jurist and sociologist whose writings shaped French administrative law in the late 19th and early 20th century.
Hauriou taught public law at the University of Toulouse since 1888, and constitutional law since 1920. His work gave French administrative law a new dogmatic basis, including through his textbooks Précis de droit administratif et de droit public général (1892), Précis élémentaire de droit administratif (1925), Précis de droit constitutionnel (1923) and Principes de droit public (1910).
