Paul Jules Antoine Meillet (; 11 November 1866, Moulins, France – 21 September 1936, Châteaumeillant, France) was one of the most important French linguists of the early 20th century. He began his studies at the Sorbonne University, where he was influenced by Michel Bréal, Ferdinand de Saussure and the members of the "L'Année Sociologique". In 1890, he was part of a research trip to the Caucasus, where he studied the Armenian language. After his return, de Saussure had gone back to Geneva so he continued the series of lectures on comparative linguistics that the Swiss linguist had given.
