The boys' 1500 metres at the 2015 World Youth Championships in Athletics was held on 15 and 17 July.

The first 800 m was run in just 2:11.40, leading to a slower final time and less qualifiers coming from the first heat.

[1] Taki again chose a frontrunning tactic to use in the finals, with only his countryman Lawi Kosgei willing to stick with the early pace.

Taki began his kick with 600 metres remaining, allowing him to break Robert Biwott's old championship record by 0.39 seconds.

[2] Ethiopia's Mulugeta Assefa chose the opposite tactic, taking a slow, conservative early pace which paid off as he passed Kosgei for the silver medal.
