David M. Kennedy (born 1958) is a criminologist, professor, action researcher, and author specializing in crime prevention among inner city gangs, especially in the prevention of violent acts among street gangs. Kennedy developed the Operation Ceasefire group violence intervention in Boston in the 1990s and the High Point Model drug market intervention in High Point, North Carolina, in 2003, which have proven to reduce violence and eliminate overt drug markets in jurisdictions around the United States. He founded the National Network for Safe Communities in 2009 to support cities using these and related strategies.
