Dmitrij Alexejevič Jaškin (Russian: Дмитрий Алексеевич Яшкин; born 23 March 1993) is a Russian-born Czech professional ice hockey player who is currently an unrestricted free agent. He most recently played for the Washington Capitals of the National Hockey League. Jaškin was selected first overall in the 2010 KHL Junior Draft by Sibir Novosibirsk, and was drafted by the St. Louis Blues in the second round, 41st overall, in the 2011 NHL Entry Draft.
His father, Alexej Jaškin, was a professional defenceman for Khimik Voskresensk in the Soviet Championship League and later Vsetín in the Czech Extraliga. Dmitrij and his older brother Michail started in the Vsetín youth system while their father played there, and they both transferred to Slavia Praha in 2008. The family has lived in the Czech Republic since 1993, when Dmitrij was eight months old.
He first played professionally for Slavia Praha of the Czech Extraliga for two seasons. Jaškin could have played in the 2011 IIHF World U20 Championship, but suffered a knee injury in an Extraliga game on 21 November, which sidelined him for six weeks and caused him to miss the tournament. He registered 10 points in 33 Extraliga games during the season as a 17-year-old, ranking him second among junior-aged players in the league.
