Asa is a Hebrew name that means "healer" or "physician" and belonged to a king of Judah praised in the Bible for removing idols from the land. The Puritans brought it to New England, where it was common into the 19th century. Asa has never left the US top 1000 since 2000 and has quietly improved from number 655 that year to number 483 in 2025, with a peak of number 450 in 2022.
