The 2011 Ladbrokes.com World Darts Championship was the 18th World Championship organised by the Professional Darts Corporation since it separated from the British Darts Organisation. Phil Taylor was the defending champion, having won the 2010 tournament. He was knocked out of the tournament at the quarter final stage by Mark Webster, who in turn was defeated by Adrian Lewis in the semi-finals. Lewis went on to win the tournament, beating Gary Anderson 7–5 in the final to become only the fifth different PDC World Champion and the first to have won it without having won the rival BDO World Championship.
