David Rodney Lewis (born July 3, 1953) is a Canadian former National Hockey League (NHL) defenceman and coach.

Lewis began his playing career with the Saskatoon Blades of the Western Canada Hockey League.

He played sixteen seasons with the New York Islanders, Los Angeles Kings, New Jersey Devils, and Detroit Red Wings, scoring 36 goals and 224 points in 1,008 games.

After Lewis' playing career ended with the Red Wings in the 1987–88 season, he stayed with the team as an assistant coach.

In June 2007, Lewis was fired as coach of the Bruins by general manager Peter Chiarelli because of the team's highly inconsistent play throughout the season.
