Louis Alexandre Antoine Mizon (1853–1899) was a French explorer and colonial administrator.

Between 1880 and 1883 he was at Pierre Savorgnan de Brazza's orders, with whom he had difficulties working.

He also led a second mission in 1892 in the same places, meant in particular to establish French control over the Adamawa (in modern Nigeria), from which the Benue, the major tributary of the Niger, rises.

The plan failed, for the English protested that the claimed territory had been assigned to Britain.

He was promoted to administrateur-superieur of Mayotte, at the orders of the governor-general of Madagascar, a position he held between 5 August 1897 and 11 March 1899.
