Fitzgibbon, FitzGibbon, Fitz-Gibbon and Fitzgibbons are Irish surnames of Hiberno-Norman origin.
The surname originates with Gilbert (Gibbon) FitzJohn, who was an illegitimate son of John FitzThomas, 1st Baron Desmond (died 1261); the line of Anglo-Norman aristocracy in Ireland descended from Gilbert became known as Fitzgibbon. Fitzgibbon means "son of Gibbon", derived from Norman French fiz/fitz (meaning "son") and Gibbon (a Norman French affectionate form of the name Gilbert). The Gaelicised form of Fitzgibbon is Mac Giobúin.
