Matthew David Cooke (born September 7, 1978) is a professional ice hockey player currently playing for the Pittsburgh Penguins of the National Hockey League. His playing style has earned him a reputation of being a "pest" and he is known for his ability to aggravate opponents. Cooke has been suspended repeatedly during his career for delivering blind-side hits and head-shots that injured opposing players, and his track record was an important factor influencing NHL rule changes intended to deter such conduct. Cooke won the Stanley Cup with Pittsburgh during the 2008–09 NHL season. Although he is no longer a member of the Vancouver Canucks' organization, he is still active in the Vancouver community with his wife as they run The Cooke Family Foundation of Hope.
