Harold Lang Winkler (March 20, 1894 – May 29, 1956) was a Canadian ice hockey goaltender.

He would also play with the Boston Bruins who acquired him from the Rangers in a cash transaction on January 17, 1927.

According to Winkler's obituary in the May 31, 1956 edition of the Montreal Gazette, he was given the unflattering nickname "Baldy" because he had lost his hair at an early age.

Winkler wore a modified baseball cap in goal partly because rival fans often threw objects at his hairless pate.

He played the whole season in the minors, as teams carried only one goaltender the backup goaltender would play for the teams minor league affiliate, for Winkler this was the Minneapolis Millers the Boston Bruins minor league team in the AHA.
