Jasiah is a modern American name that reads as a blend of Josiah and the fashionable J-names of the 2000s; it is usually connected to the Hebrew Josiah, "God supports" or "God heals", though it has no biblical history of its own. The -iah ending gives it the sound of the Old Testament names Isaiah and Jeremiah. Jasiah entered the US top 1000 in 2006, peaked at number 467 in 2022 and ranks number 498 in 2025.
