Gilleoin is Scottish Gaelic in Origin.

Gilleoin is a Scottish Gaelic masculine name built from gille "servant, devotee" and Eòin, the Gaelic form of John, giving the meaning "servant (devotee) of John," usually understood as a dedication to Saint John. The gille + saint's-name pattern was widespread in medieval Gaelic naming.

The name appears in northern Scottish records in the 12th-13th centuries, notably with Gilleoin na h-Àirde ("of the Aird"), a regional lord later remembered as ancestor to several Ross and Moray kindreds, sometimes linked to Clann Ghille Andrais (Clan Gillanders). Spellings vary: Gilleòin, Gilleain, or Gillean; Anglicised forms include Gilleon and Gillion. Related patronymics are Mac Gille Eòin or MacGilleoin, while the closely allied personal name Gillean underlies the surname MacLean (Gaelic MacGill-Eain). Today Gilleoin is rare but occasionally revived in Gaelic and Scottish-heritage circles. Approximate pronunciation: GIL-yawn.
