The surname Mannion is of Irish origin, with its roots in the Gaelic name Ó Mainnín, signifying a descendant of a person named Mainnín. The element Mainnín derives from the Irish word mainn, meaning monk, thereby indicating that the original bearer was likely associated with a monastic household or was a son of a monk.

In the West of Ireland, and especially within the borders of County Galway, the name Mannion is most frequently encountered. The sept whose name was recorded as O' Mainnin occupied the barony of Tiaquin and held the castle of Clogher as the seat of their lineage. While they were a prominent clan in the region known as Hy-Many, genealogical evidence shows that the Mannions were not descended from the Hy-Many dynasties; rather, their ancestors belonged to the ancient pre-Gaelic Pictish rulership that once governed that part of the island.

Various orthographic forms have persisted through the centuries, including Mannin, Manion, Mannion, Manning, Manan, Manin, Manon and Menon. The form Manning also exists as an English surname, particularly among families in Dublin and Cork, and is usually of Anglo descent.

The earliest extant church record that captures the spelling of the family name in the British Isles is that of a John Mannyng, who entered into matrimony with Dorathy Ulcott on 1 July 1540 at St. Margaret's in Westminster, during the reign of King Henry the Eleventh of England. Subsequent documents show the patronym ×for example, Elisabeta Manon who was baptised at St. Johns in Limerick on 28 February 1730, and the twins, John and Mary Mannion, recorded on 14 November 1790 at Moira in County Down. In London, the marriage of Ann Manion to Thomas Higgins appeared on 18 January 1827 at St. Martin in the Fields.

Through these historical attestations, the surname Mannion demonstrates a continuity of Irish heritage that flourished in the western provinces, while simultaneously revealing connections to anglicised forms and broader Christian naming practices of the period.
