'''Néon''' je [[kemijski element]], ki ima v [[periodni sistem elementov|periodnem sistemu]] simbol '''Ne''' in [[atomsko število]] [[10 (število)|10]]. Ta brezbarvni, skoraj [[inertnost|inerten]] [[žlahtni plin]] daje značilen rdečkast sijaj, ko se uporablja v elektronkah in [[neonska svetilka|neonskih svetilkah]], v zraku pa ga najdemo v sledeh.
