Mario Lessard (born June 25, 1954) is a Canadian former professional ice hockey goaltender.
Born in East Broughton, Quebec, Lessard began his National Hockey League career with the Los Angeles Kings in 1978, the team he would play his entire NHL career with.
Early in overtime of that game, Lessard mishandled the puck 40 feet in front of his net as he attempted to beat Glenn Anderson to the puck and stop a breakaway; with the net wide open and defenceman Mark Hardy trying to act as goalie, the Oilers Mark Messier shot the puck over the open net.
After the game Lessard lamented that his mistake nearly blew the amazing comeback.
