Leonardo Manzella (born March 1, 1947), best known as Leonard Mann, is an Italian-American film actor. He played numerous leading roles between 1969 and 1989, especially in Spaghetti westerns and "poliziotteschi".

He was discovered by film-producer Manolo Bolognini as he was walking along Via Veneto and Bolognini, impressed by his face that reminded him of Franco Nero and Terence Hill, immediately put him on the screen, launching his career with the leading role of Sebastian in The Forgotten Pistolero.
