★ What does Senan mean?

Irish Senán, usually traced to sean (old) with the small ending -án.

Say it right

SENan

The fada in the Irish spelling Senán marks a long second vowel, closer to SEN-awn.

The story of Senan

Senan comes from the Irish Senán, which is usually traced to sean, old, with the small ending -án. It is often explained as little old one or little wise one. Some writers have also linked it to the old name behind the River Shannon, though that idea is speculative.

The best-known bearer is Saint Senan, born around 488 near Kilrush in County Clare. After studying in Ireland and travelling to Britain and the Continent, he founded a monastery on Scattery Island, Inis Cathaigh, at the mouth of the Shannon. He is counted among the Twelve Apostles of Ireland.

The CSO counts Senan and Senán separately. The name was given quietly for decades before taking off in the 2000s, and it peaked in 2019 with 168 babies. In 2025 both spellings together reached number 33, while Senan on its own was 38th.
