The 2017 Individual Speedway Under 21 World Championship is the 2017 version of the Individual Under-21 World Championship and will be staged over three rounds, at Poznań, Güstrow and Pardubice. Australia's Max Fricke won the title in 2016.
The meeting classification was according to the points scored during the meeting, with the total points scored by each rider during each meeting credited as World Championship points. The FIM Speedway Under 21 World Champion was the rider who collected most World Championship points at the end of the series. In case of a tie between one or more riders in the final overall classification, a run-off decided the 1st, 2nd and 3rd places. For all other placings, the better-placed rider in the last meeting was the better placed rider.
