Muir is Scottish in Origin.

Muir is a concise Scottish name with dual etymologies. In Scots, muir denotes a moor or heath, yielding a topographic surname for someone who lived by the open uplands. In Scottish and Irish Gaelic, muir means “sea,” a root that also appears in older Gaelic personal names; taken as a given name, Muir can thus evoke either wild moorland or the ocean. Used for all genders but historically more common for boys, it functions chiefly as a transferred surname.

As a family name Muir (also Mure) is well attested across Lowland Scotland from the medieval period and spread to Ulster and North America. As a forename it surfaces from the 19th century, often honoring the Scottish‑American naturalist John Muir, and sees modest modern use among English‑speakers. Variant spellings include Mure and, as a looser cognate, Moore; related Gaelic forms with the sea element include Murtagh (from Muirchertach) and Muireann.
