Brian Blair "Killer" Kilrea (born October 21, 1934) is a Canadian former ice hockey head coach, general manager, and player.
It was during his time with the team's AHL franchise that the roots for what would become the National Hockey League Players Association would arise, as a direct result of the efforts of Kilrea and Alan Eagleson, then the agent for Bobby Orr.
This caught the attention of the owners of the OHL major junior Ottawa 67's and they soon offered him a coaching job, replacing Leo Boivin at the start of the 1974–75 season.
On September 3, 2008, Kilrea announced that 2008–09 would be his final season as coach of the 67's, though he plans to continue serving as general manager of the club.
He became the oldest coach in hockey history, winning career game number 1,194 by a score of 6–3 against the Mississauga Steelheads.
Kilrea served as a recurring assistant coach to Don Cherry in the CHL/NHL Top Prospects Game.
Since 1976, Kilrea has co-owned a restaurant with Nick Bouris called Chances R in Ottawa's west end.
