Isaias
ee-sy-EE-as
Isaias is the Late Latin form of Isaiah, from the Hebrew יְשַׁעְיָהוּ (Yesha’yahu) meaning “God is salvation.” This spelling appears in the Latin Vulgate Bible and in Spanish Catholic tradition.
The prophet Isaiah is a towering figure in Judaism and Christianity, authoring one of the longest books in the Hebrew Bible. The Isaias spelling preserved the Latin pronunciation across Romance languages.
Isaias peaked at No. 441 in 2023 with 705 births. In 2024 it ranks No. 446 with 703 births, holding essentially flat near its high.
What the name Isaias means
The name is overwhelmingly used within Hispanic communities in the US, where the Spanish pronunciation (ee-sah-EE-ahs) flows naturally and the biblical connection runs deep.
Four syllables - ee-ZAY-us or ee-sah-EE-ahs - differ depending on English or Spanish pronunciation. Both versions carry a prophetic, resonant quality.
Parents who want Isaiah’s meaning but a more distinctive look choose Isaias. The S-ending and Latin heritage set it apart visually on any class roster.
Its stability near 700 births per year suggests Isaias has found a sustainable niche within the top 500 that is unlikely to shift dramatically.
