Costello is an Irish name from County Mayo, Ireland, where the family held lands. It comes from the Gaelic Oisdealbhach which means "resembling a deer." The earliest known ancestor--Teag MacCostello--was recorded in 1565. Roots for this name can also be found in Italy. The family motto is Ne te quaesiveris extra which means "Seek nothing beyond your sphere."

Other spellings include "Costillo," "Costallo," "Costellow," "Caustello," "Kostello," "McCostello," and "MacCostello." Notable people with the surname include American actor Lou Costello (The Abbott and Costello Show, Africa Screams, Jack and the Beanstalk), American Olympic athlete Paul Costello (rowing), and English musician Elvis Costello. The first Costello to come to America was Honor Costello in 1756.
