The 2023 PDC World Darts Championship (known for sponsorship reasons as the 2022/23 Cazoo World Darts Championship) was a professional darts event that took place at Alexandra Palace in London, England, from 15 December 2022 to 3 January 2023. It was the thirtieth World Darts Championship to be organised by the Professional Darts Corporation since it separated from the now-defunct British Darts Organisation.

Steve Beaton made a record-extending 32nd consecutive World Championship appearance, but lost in the first round to Danny van Trijp, and Dutchman Raymond van Barneveld became the second player to make 30 World Championship appearances. Peter Wright was the defending champion, having defeated Michael Smith in the 2022 final, but he lost 4–1 to Kim Huybrechts in the third round.

Smith defeated Michael van Gerwen 7–4 in the final, winning his first world title and reaching world number one on the PDC Order of Merit for the first time. Smith hit the only nine-dart finish of the tournament in the final, with the score at 1–0 in sets to van Gerwen and 1–1 in legs, when van Gerwen had thrown eight darts at trebles and missed a dart at double 12 for a nine-dart finish himself in the same leg. Broadcasters and commentators subsequently labelled the leg as the greatest in the history of darts.

In January 2022, it was announced that online car retailer Cazoo would become the new title sponsor on a multi-year deal. The deal brought an end to 20 years of the tournament being sponsored by bookmakers, with Ladbrokes sponsoring the event from 2003 to 2014, before William Hill's sponsorship of the event began the following year. The deal was Cazoo's fifth title sponsorship within the PDC, following deals to secure the naming rights for the World Cup of Darts, the European Championship, the Grand Slam of Darts, and the Premier League Darts. Japanese company Toyo Tires also sponsored the event, with their logo being worn on the sleeves of all 96 players.

As part of a four-year contract extension signed in 2021, the event was staged at Alexandra Palace in London. The same venue has been used since the 2008 championship. The dartboard used for the event was the Winmau Blade 6 Triple Core, used for the first time at a PDC World Championship following the end of the PDC's 25-year partnership with manufacturer Unicorn in January 2022.

Dutchman Michael van Gerwen went into the event widely seen as the favourite to lift his fourth championship, with Sky Sports pundits Wayne Mardle and Mark Webster both backing him, while rival Gerwyn Price of Wales declared him as "the one to beat". Van Gerwen himself said that he had nothing to prove, but warned his rivals that "there is only more to come", but acknowledged that as he was a favourite he was a "big target". Ladbrokes, who returned to sponsoring the event as an "official betting partner", gave odds of 13/5 for Van Gerwen.

Wright's own preparations received a setback in November when his wife was rushed to hospital during the Grand Slam, following which he pulled out of the Players Championship Finals, but he told Oche magazine that he would return in time to defend his championship.

The prize money for the tournament remained at £2.5 million in total for the fifth year in a row, with the winner's share totalling £500,000. Additionally, a special jackpot of £100,000 was created by tournament sponsors Selco in the event a player hit two nine-dart finishes, with the player receiving £50,000 and the remainder split between Cancer Research UK and a member of the public chosen at random. Gerwyn Price described it as a "great initiative", particularly amid the cost of living crisis in the United Kingdom. In addition, the winner of the tournament receives the Sid Waddell Trophy, named after the former commentator who died in 2012.
