David Ross Lonsberry (February 7, 1947 – May 4, 2014) was a Canadian professional ice hockey left winger who played 15 seasons in the National Hockey League (NHL) for the Boston Bruins, Los Angeles Kings, Philadelphia Flyers and Pittsburgh Penguins.
Coveted by the Los Angeles Kings, they traded for him in 1970 for two first round draft picks, and he became a steady two-way performer for Los Angeles, scoring twenty or more goals each of his two full seasons with the Kings and being named to play in the NHL All-Star Game in 1972.
Playing on a line with Rick MacLeish and Gary Dornhoefer, his hard-nosed two-way style fit in perfectly with the "Broad Street Bullies," scoring over twenty goals in three of his six and a half seasons in Philadelphia and participating in both of the Flyers' Stanley Cup championships.
In 1978, Lonsberry was dealt for the final time to the Pittsburgh Penguins, remaining an effective player for his three years with that club.
Lonsberry finished his career with 256 goals and 310 assists for 566 points in 968 games, adding 806 penalty minutes.
