José Greco (né Costanzo Greco; December 23, 1918 – December 31, 2000) was an Italian-born American flamenco dancer and choreographer known for popularizing Spanish dance on the stage and screen in America mostly in the 1950s and 1960s.

José Greco was born as Costanzo Greco in Montorio nei Frentani to Paolo Emilio and Maria Carmela (née Bucci) Greco. He would later legally change his name. When he was 10 years old, Greco and his family moved to New York City. He began dancing in Brooklyn with his sister Norina at a young age.
