The Bill Masterton Memorial Trophy is an annual award under the trusteeship of the Professional Hockey Writers’ Association and is given to the National Hockey League player who best exemplifies the qualities of perseverance, sportsmanship, and dedication to hockey. The winner is selected in a poll of all chapters of the PHWA at the end of the regular season.
