The Norris Trophy is an annual award presented to the best defenseman in the NHL (National Hockey League). It is named after James Norris, a former owner of the Detroit Red Wings, and has been awarded since the 1953-54 season. The trophy recognizes players who excel in both defensive play and offensive contributions. Voting for the Norris Trophy is conducted by the Professional Hockey Writers' Association at the end of each regular season. The winner is determined based on a combination of individual performance and overall impact on their team's success.
