The name Diarmuid is an Irish masculine given name derived from the old Irish words "diar" meaning "free" or "without" and "muit" meaning "shame" or "blemish". The name is believed to have originated in the 5th or 6th century AD among the Gaelic peoples of Ireland.
One of the earliest known historical references to the name Diarmuid comes from the Irish mythological text, the Fenian Cycle of Irish mythology.
