Meaning & Origin

If you're considering Siobahn, you're looking at a name that fewer than 82 families have ever chosen in the U.S. That kind of rarity is intentional — it signals that the name was chosen for its sound, its personal meaning, or a family connection rather than a trend.

The sharp, distinct ending gives Siobahn a crisp, modern feel that pairs easily with most surnames.

Siobahn is not in the current top 1,000 girl names nationally, making it an uncommon choice — though your state or community may differ.

Siobahn is a girl's baby name of Irish origin, an alternate spelling of Siobhan, the Irish form of Joan, derived ultimately from the Hebrew Yochanan meaning 'God is gracious.'

Siobhan is one of Ireland's most beloved traditional names, pronounced "shih-VAWN" — a sound that surprises many English speakers who encounter it for the first time. This spelling variant Siobahn preserves the name's Irish identity while slightly adjusting the visual form.

EtymologyShow more

In the American context, Siobahn is a girl's name with several decades of recorded use (19782012). Its Irish roots connect it to a broader naming tradition, but in practice, American usage often reshapes names — adding nicknames, shifting pronunciation, and building new associations that diverge from the original cultural context.

With 82 total births, Siobahn exists at the edges of the American naming landscape — a name known primarily to the families who carry it, giving it an intensely personal character.
