Meaning & origin

Osiah is a modern name that first appeared in U.S. birth records in 1999, reflecting a late 20th-century trend of inventing names by combining familiar biblical suffixes. As of 2025, it ranks 2480th, with a rarity of approximately 1 in 31,631 births, and has been climbing steadily since 2006. Its peak year so far is 2025, indicating growing but still modest use. The name is most popular in Tennessee and California. While its exact origins are uncertain, Osiah fits alongside other 'iah'-ending names that have gained traction in recent decades.

Osiah is a name that emerged in the late 20th century, first recorded in U.S. data in 1999. It may be a modern fusion of elements from biblical names like Josiah (meaning 'Yahweh supports') and Isaiah ('Yahweh is salvation'), or a respelling of the rare name Oziah. Its rise since 2006 suggests a contemporary invention influenced by popular 'iah'-ending names.
