Gilleann is Irish (Gaelic), Scottish Gaelic in Origin.

Rooted in the Gaelic tradition, Gilleann is a masculine name built from gille, “servant, youth,” and Eoin, the Gaelic form of John, yielding the devotional sense “servant of (Saint) John.” The construction belongs to a broader medieval pattern of theophoric Gaelic names (compare Gillebrìde and Gille Chrìost). While the elements are shared across Scottish and Irish Gaelic, the name is most strongly linked to the Scottish Highlands.

The name is best known through Gillean na Tuaighe (“of the Battle Axe”), the 13th‑century progenitor of Clan Maclean; from his name comes the surname Mac Gille Eóin, now MacLean/McLean. Documented medieval and early modern spellings include Gilleann, Gillean, Gilleain, Gilleon, and the two‑word form Gille Eoin. Anglicized variants include Gillan, Gillen, and Gillon. Though sometimes confused with the English feminine Gillian (from Latin Julianus), Gilleann is etymologically distinct and traditionally male. Today it is rare but occasionally revived as a heritage name.
