Meaning and history
Jason comes from the Greek name Ἰάσων (Iason), meaning “healer,” from ἴασις (iasis) “healing,” which in turn comes from ἰάομαι (iaomai) “to heal.” In Greek mythology, Jason led the Argonauts and sought the Golden Fleece to reclaim the throne of Iolcus after his uncle Pelias overthrew his father Aeson; he married the sorceress Medea, who helped him obtain the fleece and kill Pelias before later turning against him when he fell in love with another woman. The name also appears in the New Testament, where it belongs to the man who sheltered Paul and Silas, and in that context it may be a Hellenized form of a Hebrew name. It was not used in England until after the Protestant Reformation.
Jason moved from #148 to #165 for boys between 2024 and 2025. Its highest annual birth count came in 1977, with 55,631 births.
