Igor Nikolayevich Larionov (Russian: Игорь Николаевич Ларионов; born December 3, 1960) is a Russian retired professional ice hockey player, known as "The Professor". Along with Viacheslav Fetisov, he was instrumental in breaking the barrier that stopped Soviet players from joining the National Hockey League (NHL). He primarily played the centre position, and is considered one of the best passers of all time. Larionov won three Stanley Cup championships with the Detroit Red Wings (1997, 1998, 2002) and was inducted as an Honored Member of the Hockey Hall of Fame on November 10, 2008.
On the international stage, playing for the Soviet Union, Larionov centered Vladimir Krutov and Sergei Makarov on the famed "KLM Line". Along with defensemen Viacheslav Fetisov and Alexei Kasatonov, they formed the "Green Unit", so named because they wore green jerseys in practice. All five players also played for CSKA Moscow.
He won two golds (1984, 1988) and one bronze for Russia (2002) in the Olympics, and four golds (1982, 1983, 1986, 1989), one silver (1987), and one bronze (1985) in the World Championships. He was an instrumental member of the Soviet squad that won the 1981 Canada Cup (this tournament was the coming out of the KLM Line) and played in the 1984 and 1987 events as well. He then played for Russia in the 1996 World Cup of Hockey.
