The National Basketball League Coach of the Year is an annual National Basketball League (NBL) award given since the 1980 NBL season to the best head coach of the regular season. At the season's end, each club's Head Coach, one Assistant Coach and the Team Captain vote on the Coach of the Year in a 3-2-1 format (3 votes being indicative of the most deserving). Voters are not allowed to vote for the coach of their own team. The winner receives the Lindsay Gaze Trophy, which is named in honour of legendary NBL coach and Basketball Hall of Famer Lindsay Gaze, who guided the Melbourne Tigers to two NBL Championships over a long and celebrated career.
