Harry Frost (August 17, 1914 – March 1973) was a Canadian professional ice hockey forward who played five games in the National Hockey League for the Boston Bruins, including one in playoffs for Stanley Cup winning Boston Bruins in 1939. Boston honoured him by putting his name on the Stanley Cup. He was born in Kerr Lake, Ontario.
He played for the senior Frood Tigers in 1934-35 and then joined the Hershey Bears with whom he played eight seasons (interrupted by his short stint with the Bruins). Frost then served two years in the military (1943-45) before returning to the minor pros.
He retired in 1952.
