Carlo Teodoro Duclère (Naples, 1812-1869) was an Italian landscape painter, associated with the School of Posillipo.
His father, Jacques-François Théodore Duclère, born around 1788, was from Seine-et-Marne, France, and came to Italy during the Napoleonic Wars.
He met and married Teodoro's future mother, Costanza Lepori, in Rome and they settled in Naples, where he took a job as a customs officer.
