The 2018 International Darts Open was the twelfth of thirteen PDC European Tour events on the 2018 PDC Pro Tour. The tournament took place at the SACHSENarena, Riesa, Germany from 14–16 September 2018. It featured a field of 48 players and £135,000 in prize money, with £25,000 going to the winner.
Peter Wright was the defending champion after defeating Kim Huybrechts 6–5 in last year's final, but he was defeated 6–4 by Ryan Searle in the second round.
Gerwyn Price won his first European Tour title by beating Simon Whitlock 8–3 in the final. This tournament was also the first in European Tour history in which none of the top 4 seeds reached the quarter-finals.
