Meaning & origin
Onna is a rare and delicate name with an uncertain etymology. First recorded in the United States in 1927, it has never achieved widespread use, though it saw a modest peak in 2015 when it reached its highest rank. In 2025, it stood at rank 8,362, with approximately 1 in 133,939 newborn girls receiving the name. Its trajectory has been falling since 2015. The name's similarity to the Irish Oona and the Latin Una may appeal to parents seeking a short, vowel-heavy name with a gentle sound. Its obscurity offers a degree of uniqueness, though its lack of clear meaning or cultural roots may be a consideration for some.
The origin of Onna is unclear. It may be a modern coinage using the popular -na ending, or a variant of names like Oona (of Irish origin, meaning 'lamb') or Una (of Latin origin, meaning 'one'). It has been used in the United States since the early 20th century, with a small but consistent presence.
