The 2018 ICC World Cricket League Division Four was an international cricket tournament that took place during April and May 2018 in Malaysia. It formed part of the 2017–19 cycle of the World Cricket League (WCL) which determined the qualification for the 2023 Cricket World Cup. The top two teams were promoted to the 2018 ICC World Cricket League Division Three tournament and the bottom two teams were relegated to Division Five.
Two of the three final round of group stage matches finished as a no result because of rain. Per the rules of the tournament, the matches were replayed on the final day of the competition, with the play-off round scrapped and used as a reserve day. Therefore, the final league standings were used to determine the promotion and relegation places.
Uganda won the tournament and were promoted to Division Three, along with runners-up Denmark. Vanuatu and Bermuda finished in fifth and sixth respectively, and were relegated to Division Five. Hosts Malaysia finished third and Jersey finished fourth, therefore both team remained in Division Four. Ben Stevens of Jersey was named as the player of the tournament.
