Cinneidigh is Irish in Origin.

Of Irish Gaelic origin, Cinneidigh represents the early medieval personal name recorded in Old Irish as Cennétig and in later Irish orthography as Cinnéidigh/Cinnéide, source of the surname Ó Cinnéide (“descendant of Cinnéidigh”). The etymology combines ceann “head” with a debated second element: either éide “armour, helmet,” yielding “helmet-headed,” or éidigh “ugly,” giving “ugly-headed.” Most modern treatments prefer the martial “helmeted head.”

The name appears in annals borne by Cennétig mac Lorcáin, 10th‑century ruler of Thomond and father of Brian Boru. Through Ó Cinnéide it became the widely distributed Kennedy in Ireland and Scotland, later a common Anglicized surname and, from the 20th century, a unisex given name in the United States. Variants include Cennétig (Old Irish), Cinnéidigh/Cinnéide (Modern Irish), Ó Cinnéide (patronymic), and Anglicizations Kennedy, Kenedy, Kennedie. As Cinneidigh, the traditional Gaelic given form is rare today.
