Meaning and history
Aäron comes from the Hebrew name אַהֲרֹן (ʾAharon), probably of unknown Egyptian origin, though some theories propose a Hebrew derivation with meanings such as “high mountain” or “exalted.” In the Old Testament, Aaron is Moses’ older brother, who spoke for him in appealing to the pharaoh for the Israelites’ release, and whose rod was used to perform miracles and plagues; after the Exodus and the arrival at Mount Sinai, God appointed him the first high priest of the Israelites and promised that his descendants would form the priesthood. As an English name, Aaron has been used since the Protestant Reformation, and it was borne by the American politician Aaron Burr (1756–1836), known for killing Alexander Hamilton in a duel.
Aaron has unusual staying power. It appears in the US records as early as 1880 and still ranks #80 for boys in 2025. Its highest annual birth count came in 1989, with 15,308 births.
