About Oisin

Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.

Ossian is another version, reflected in the eighteenth century Ossianic poems of James Macpherson, which transformed him into a Scottish hero and also popularized the names Oscar, Fingal, Selma and Malvina.

Pronounced OH-sheen; ush-EEN.

As of October 2026, Oisin ranked #4660 in US births in 2025 SSA, peaked at #3546 in 2020.
