The 2019 PDC Unicorn World Youth Championship was the ninth edition of the PDC World Youth Championship, a tournament organised by the Professional Darts Corporation for darts players aged between 16 and 23.

The group stage and knock-out phase from the last 32 to the semi-finals were played at Robin Park Centre, Wigan, on 4 November 2019.

Belgium's Dimitri Van den Bergh was the two-time defending champion after defeating Martin Schindler of Germany 6–3 in the 2018 final, but he was unable to defend his title, as he was over the age limit.

Luke Humphries won the tournament for the first time with a 6–0 win over Adam Gawlas in the final.

72 players from the final 2019 PDC Development Tour Order of Merit were set to qualify, as were 23 international qualifiers and Max Hopp, who was ranked in the top 32 of the main PDC Order of Merit at the start of the year and therefore took the top seeding place.
