John Henry "Yip" Radley (born June 27, 1908 in Ottawa, Ontario - August 19, 1963) was a retired professional ice hockey defenceman who played 19 games in the National Hockey League. He would play with the Montreal Maroons.
He started out in his hometown Ottawa City Senior League with the Ottawa Rideaus and the Ottawa Montagnards from 1926 to 1930. The New York Americans signed him as a free agent in 1930 and, after keeping him for the first game of the 1930-31 season, sent him down to the New Haven Eagles.
Radley spent six seasons in the minor pros until the Montreal Maroons gave him a chance in 1936. Injuries to Maroons players kept him in the lineup for several months. He played in 17 games and scored an assist.
