David Pastrnak (Czech pronunciation David Pastrnak born 25 May 1996) is a Czech professional ice hockey right winger for the Boston Bruins of the National Hockey League. Nicknamed "Pasta", Pastrnak was selected by the Bruins in the first round, 25th overall, of the 2014 NHL Entry Draft and made his NHL debut that year. Internationally Pastrnak has played for the Czech national team at both the junior and senior level, including at four World Championships.

Pastrnak's father, Milan, wanted him to play ice hockey. Following a lengthy battle with cancer, Milan died in 2013. Pastrnak cites this as the reason why he began practicing and training so hard, hoping to make it as a hockey player for his father.

During the 2011-12 season, Pastrnrak led the Czech under-18 league in goals (41) and points (68). After being drafted by the Boston Bruins in the 25th pick overall in the 2014 NHL Entry Draft, Pastrnak signed a three-year, entry-level contract on 15 July 2014.
