The 2015 FIBA Under-19 World Championship (Greek: Παγκόσμιο Πρωτάθλημα FIBA Under-19 2015) was the 12th edition of the FIBA U19 World Championship, the biennial international men's youth basketball championship contested by the U19 national teams of the member associations of FIBA. It was hosted by Heraklion, Greece, from 27 June to 5 July 2015. It was the third time that Greece hosted the tournament since 1995.
As a result of FIBA rules changes, made effective as of 1 October 2014, this tournament marked the first time that the FIBA Under-19 World Championship used instant replay to review controversial plays and where players were allowed to wear any jersey with numbers from "00" to "99".
The United States won their sixth title by defeating Croatia 79–71 in the final.
