Oisin

Meaning of Oisin

Oisin is a masculine name of Irish Gaelic origin, derived from the word oisín, meaning “little deer,” and historically borne by the poet-warrior son of Fionn mac Cumhaill in Irish legend. Pronounced uh-SHEEN (/əˈʃiːn/) in both Irish and English contexts, it retains a consistent phonetic profile. Analysis of U.S. Social Security data from 1991 through 2024 indicates that Oisin has occupied a steady niche in the national rankings—fluctuating between the 700- and 900-position band—with 26 newborns given the name in 2024 (rank 898) and a peak of 31 in 2020 (rank 887). This measured yet persistent usage suggests that Oisin appeals to parents seeking a name with clear pronunciation, Celtic heritage, and a direct link to Ireland’s mythological tradition.
