The 2018 U-23 Baseball World Cup, officially II U-23 Baseball World Cup, is the second edition of the U-23 Baseball World Cup tournament, third since the tournament's inception in 2014 as the 21U Baseball World Cup. The tournament was held at Edgar Rentería Baseball Stadium in Barranquilla and 18 de Junio Baseball Stadium in Montería, Colombia. Originally the host to the tournament was awarded to Nicaragua and would be held in Managua, but due to 2018–2020 Nicaraguan protests, WBSC subsequently decided to move the tournament to Colombia.
