The 2018 William Hill World Darts Championship was a darts event, held between 14 December 2017 and 1 January 2018 at the Alexandra Palace in London, United Kingdom. It was the 25th World Championship organised by the Professional Darts Corporation since it separated from the British Darts Organisation.
Michael van Gerwen was the defending champion, but lost 6–5 in sets to Rob Cross in the semi-finals, with the score at 5–5 in sets and with van Gerwen leading 5–4 in legs he missed 5 match darts to beat Cross. Cross forced an 11th and sudden death leg, van Gerwen missed a 6th match dart before Cross hit double 8 to win an epic semi-final and reach his first world final. Cross went on to win the World Championship on his debut by defeating Phil Taylor 7–2 in the final. Cross only turned professional 11 months prior to the event. This was Taylor's 29th and final World Championship, surpassing the record of 28 appearances he jointly held with John Lowe.
Jamie Lewis became the first player to reach the semi-finals after entering the championship through a preliminary round event, first introduced at the 2004 Championship. Lewis eventually fell to Taylor in the semi-final, by a score of 6–1.
