Kimmo Timonen (born March 18, 1975) is a Finnish professional ice hockey defenseman who plays for the Philadelphia Flyers of the National Hockey League (NHL). He is an alternate captain for the Flyers during away games.
Timonen was the youngest player to represent Finland at the 1993 IIHF World Junior Championships at the age of 17. He recorded the second-highest shot total in the tournament with 44.
Timonen was drafted by the Los Angeles Kings in the tenth round, 250th overall, of the 1993 NHL Entry Draft. After the draft, he continued to play in his native Finland for several years, first for KalPa and then later for TPS. In 1998, Timonen played on the bronze medal-winning Finnish Olympic team in Nagano. Shortly after the Olympics, the Kings traded him along with Jan Vopat to the Nashville Predators organization (the team not yet having begun play) in agreement that Nashville would not select Garry Galley in the 1998 NHL Expansion Draft.
