Muireagan is Irish, Scottish Gaelic in Origin.

Muireagan is a Gaelic given name, attested in Irish as Muireagán and also found in Scottish Gaelic without diacritics. It likely stems from Old Irish muir “sea” combined with the diminutive suffix -agán/-án, yielding interpretations such as “little sea” or “sea-born.” The name appears in medieval Gaelic usage and survives in patronymics: the surname Ó Muireagáin was later anglicized as Morgan, helping to preserve the form even as the given name itself became rare.

Variants and related forms include Muireagán (Irish spelling with fada), Muireagan (Scots Gaelic/modern simplification), and the cognate Muirgán. Anglicized equivalents most commonly appear as Morgan, which has become unisex in English, though Muireagan was historically masculine. It is sometimes confused with Muireadhach (source of Murray/Murdoch) or with the feminine Muireann; it is unrelated to the mythic Morrígan (“great queen”). Today, Muireagan sees occasional revival among Gaelic-language advocates seeking maritime-themed heritage names.
