Antonio del Rincón (1566 – March 2, 1601) was a Jesuit priest and grammarian, who wrote one of the earliest grammars of the Nahuatl language (known generally as the Arte mexicana, MS. published in 1595). A mestizo native of Texcoco from the early decades of the Viceroyalty of New Spain and descendant of the tlatoque (ruling nobility of Texcoco), del Rincón knew the language of the indigenous Nahua peoples intimately. His grammar ranks alongside those of Andrés de Olmos and Alonso de Molina as an influential primary source for the language as spoken in the post-conquest period.
