Shea is Irish in Origin.

Shea (pronounced SHAY) is an Anglicized Irish given name and surname derived from Ó Séaghdha, meaning “descendant of Séaghdha.” The Old Irish personal name Séaghdha is glossed in medieval sources as “stately” or “admirable,” and modern Irish tradition often interprets it as “dauntless” or “hawk‑like,” giving Shea an appealing sense of poised courage. In contemporary Irish, the surname appears as Ó Sé, commonly rendered O’Shea in English.

As a given name, Shea transitioned from surname use in Ireland to broader Anglophone popularity in the late twentieth century, especially in the United States and Canada. It is firmly unisex, borne by athletes, artists, and writers, and familiar through New York’s Shea Stadium (named for attorney William A. Shea). Common variants and spellings include Shay and Shae; diminutives are rare. Related surnames include O’Shea and Shea without the prefix.
