Alfredo de Oro (April 28, 1863 – April 22 or 23, 1948) was a Cuban professional carom billiards and pool player who several times held the world title in both three-cushion billiards and straight pool simultaneously.
He was posthumously inducted into the Billiard Congress of America's Hall of Fame in 1967, one of the very few non-Americans to receive the honor.
He was ranked number 4 on the Billiards Digest 50 Greatest Players of the Century.
