Maxime Leroy (28 March 1873 – 15 September 1957) was a French jurist and social historian.
Maxime Leroy studied law at the university of Nancy, where he obtained his doctorate in 1898.
A friend of Victor Griffuelhes and Alphonse Merrheim, he devoted his first works to the development of trade unionism and its legal and social impact.
In 1909 he founded the "Société des amis du lac" at Soorts-Hossegor, where writers such as J.-H. Rosny jeune, Paul Margueritte and Gaston Chérau had been meeting for some years.
His most important work, Histoire des idées sociales en France, was published in three volumes between 1946 and 1954.
