The 2005 Individual Speedway Junior World Championship was the 29th edition of the World motorcycle speedway Under-21 Championships.

The final was won by Krzysztof Kasprzak of Poland, after the meeting was stopped early after just 12 heats due to heavy rain and dangerous track conditions. Kasprzak and Tomáš Suchánek both finished on 8 points after three rides and Kasprzak was declared the winner after coin flipping. Freddie Lindgren took the bronze medal from Paweł Hlib by virtue of having two race wins from his three races.
