Nodar David Kumaritashvili (Georgian: ნოდარ დავით ქუმარიტაშვილი; pronounced [nɔdar kʰumaritʼaʃvili]; November 25, 1988 – February 12, 2010) was a Georgian luger, who suffered a fatal crash during a training run for the 2010 Winter Olympics competition in Whistler, Canada, on the day of the opening ceremony. He became the fourth athlete to have died during Winter Olympics preparations, after British luger Kazimierz Kay-Skrzypeski, Australian skier Ross Milne (both Innsbruck 1964), and Swiss speed skier Nicolas Bochatay (Albertville 1992), and the sixth athlete to die in either a Summer or Winter Olympic Games.

Kumaritashvili, who first began to luge when he was 13, came from a family of seasoned lugers; a relative of his was the founder of organised sledding Georgia, and his father competed when he was younger. A cousin of Kumaritashvili's father was the head of the Georgian Luge Federation; Kumaritashvili himself began competing in the 2008–09 Luge World Cup, where he finished 55th out of 62 racers. Outside of luge, Kumaritashvili had been a student at the Georgian Technical University, where he earned an economics degree in 2009.
