Antoine Ritti (6 February 1844, Strasbourg - 23 January, 1920, Paris) was a French psychiatrist.
Ritti, whose uncle was Andreas Räss, the Bishop of Strasbourg, seemed originally destined to become a priest.
In 1878 he was appointed to a doctor's office in Charenton, a position he held until his retirement in 1909.
During these years he wrote numerous eulogies and obituaries published in the Annales médico-psychologiques.
Ritti is buried in Père-Lachaise cemetery, in the tomb of the families Bouclier de la Fizelière.
