The 2018 Unibet Premier League Darts was a darts tournament organised by the Professional Darts Corporation – the fourteenth edition of the tournament. The event began on Thursday 1 February at the 3Arena in Dublin and ended with the play-offs at The O2 Arena in London on Thursday 17 May. This was the first year that the tournament is sponsored by Unibet.

Premier League Darts, known for sponsorship purposes in 2024 as BetMGM Premier League Darts, is a darts tournament which launched on 20 January 2005 on Sky Sports. Now played weekly from February to May, the event originally started as a fortnightly fixture in small venues around the United Kingdom. The tournament originally featured seven players, gradually expanded to ten by 2013, before reduced again from 2022 to eight players from the Professional Darts Corporation circuit competing in a knockout style format, with nights also hosted in Europe at different venues. The top four players in the PDC Order of Merit are joined by four wildcard selections to make up the eight-person field. Alongside the World Championship and the World Matchplay, it is considered part of the sport's Triple Crown.
