Nestor, or Néstor, is a given name of Greek origin. In Greek mythology it comes from that of Nestor, the son of Neleus, the King of Pylos and Chloris.^[1] The Greek derivation is from a combination of νέομαι, néomai, 'go back', and νόστος, nóstos, 'one who returns from travels'.^{[citation needed]}

The name is also found in Russia, Portugal, and France, with variants in Finland (Nestori), Italy (Nestore), and Spain (Néstor).^[1]
