David Chisnall (born 12 September 1980) is an English professional darts player from St Helens who plays in Professional Darts Corporation (PDC) events. He began his career participating in the British Darts Organisation (BDO) and was the runner-up in their World Championship in 2010. He switched to the PDC a year later. He has won 15 Pro Tour events. Since his switch to the PDC, Chisnall is probably best known for defeating Phil Taylor in the 2012 World Championship, for reaching the final of the 2013 World Grand Prix where he was beaten 6–0 by Taylor and for reaching the final of the 2014 Grand Slam of Darts, losing a much closer match 16–13, again to Phil Taylor. He is yet to win a major title. He hit his only televised nine-dart finish in the 2015 Grand Slam of Darts against Peter Wright. He has won 15 PDC ranking events. Chisnall's manager is Roger Schena, who often tours with him during tournaments.
