Antonio Cayetano Rivera Ordóñez (born 13 January 1977 in Madrid, Spain) is a Spanish torero or bullfighter.

He belongs to a long line of famous bullfighters: his great-grandfather was Cayetano Ordóñez, who fought under the name 'El Niño de la Palma', and was the inspiration for the young matador in Ernest Hemingway's novel The Sun Also Rises.

Antonio is the subject, with Cayetano's torero great-uncle Luis Miguel Dominguín, of Hemingway's book The Dangerous Summer.

In 2007 he was on the cover of Vogue with Penélope Cruz for an editorial titled 'Made in Spain' shot by Annie Leibovitz.
