Séamus

'''' () is an Irish male given name, of Hebrew origin via Latin. It is the Irish equivalent of the name James. The name James is the English New Testament variant for the Hebrew name Jacob. It entered the Irish and Scottish Gaelic languages from the French variation of the late Latin name for Jacob, ; a dialect variant of , from the New Testament Greek (), and ultimately from Hebrew word (), i.e. Jacob. The name comes either from the Hebrew root ʿqb meaning "to follow, to be behind" but also "to supplant, circumvent, assail, overreach", or from the word for "heel", ʿaqeb''. It can also be taken to mean "may [God] protect". The traditional explanation for the name follows that it was given to the patriarch Jacob when he was born, as he was grasping his twin brother Esau's heel, though this is a folk etymology.

Other variant spellings in Irish include , and Seumus. It has also been anglicised as Shaymus, Seamus, Seamas, Sheamus and Shamus. Diminutives include ', ' and ''.
