The Lady Byng Memorial Trophy is an annual award given to the player adjudged to have exhibited the best type of sportsmanship and gentlemanly conduct combined with a high standard of playing ability. The winner is selected in a poll of the Professional Hockey Writers' Association at the end of the regular season; each individual voter ranks his top five candidates on a 10-7-5-3-1 points system. Three finalists are named and the trophy is awarded at the NHL Awards ceremony after the Stanley Cup Playoffs.
Lady Byng, wife of Canada's Governor-General at the time, presented the Lady Byng Trophy in 1925. She decided the trophy's first winner would be Frank Nighbor of the Ottawa Senators. Late in the season, Lady Byng invited Nighbor to Rideau Hall, showed him the trophy, and asked him if the NHL would accept it as an award for its most gentlemanly player. When Nighbor said he thought it would, Lady Byng, much to Nighbor's surprise, awarded him the trophy.
