Oneil is Irish in Origin.
Oneil is a modern given-name spelling of the Irish surname O'Neill, from Gaelic Ó Néill "descendant of Niall." Niall is an early Irish personal name of debated meaning, often interpreted as "champion," "cloud," or "passionate," borne by the legendary Niall of the Nine Hostages. The powerful Uí Néill dynasty of Ulster spread the surname widely across Ireland and, through migration, into Scotland and the wider Anglophone world.
Adopted as a first name in the 20th century, Oneil fits the surname-as-given-name trend and sees particular use in North America and the Caribbean. Pronounced oh-NEEL/oh-NEIL, it conveys both ancestral pride and the valence of "champion" via Niall. Close variants include O'Neil, O'Neill, O'Neal, Oneal, and Oniel; related given names are Niall, Neil, and Neal, with feminine forms such as Neila and Nia occasionally used. Diminutives like Nel or Neil occur in informal use.
