Muireann is Irish in Origin.

Muireann is an Irish Gaelic feminine name, recorded in Old Irish as Muirenn. It is commonly interpreted as “sea-white” or “sea-fair,” from muir “sea” combined with an element denoting brightness or fairness; some gloss it more generally as “of the sea.” The name appears throughout early Irish literature and hagiography, reflecting its long-standing presence in the Gaelic world.

Well attested in the medieval annals for abbesses and noblewomen, Muireann persisted in local tradition and enjoyed a notable revival during the 20th-century Irish-language movement, remaining familiar in Ireland today. Variants include the archaic Muirenn and the affectionate diminutive Muirín. Modern Anglicized spellings such as Murren and Murron are also encountered. While related maritime-themed names like Muirgen (“sea-born”) occur in legend, they are distinct forms. Muireann’s blend of lyrical sound and sea-rooted imagery gives it a timeless, distinctly Irish character.
