Aldo Reno Guidolin (June 6, 1932 – November 8, 2015) was a Canadian professional ice hockey defenceman and coach. He played in the National Hockey League with the New York Rangers between 1952 and 1956. The rest of his career, which lasted from 1952 to 1969, was mainly spent in the American Hockey League. After his playing career, Guidolin became a coach, and was the head coach of the NHL's Colorado Rockies during the 1978–79 season.
Guidolin played for the next fourteen seasons with Springfield Indians, Cleveland Barons and Baltimore Clippers, serving as a bruising defender with an offensive flare.
He is the first cousin of fellow NHL player and coach Bep Guidolin, who was the first coach of the Kansas City Scouts when they joined the NHL in 1974. The Scouts moved from Kansas City to Denver after two seasons to become the Rockies.
