The 2008 FIM Sidecarcross world championship, the 29th edition of the competition, started on 20 April and finished after twelve race weekends on 14 September 2008.

Daniël Willemsen and Reto Grütter were the defending champions, having won the title in 2007, and repeated this achievement in 2008.

The twelve races of the season were held in ten countries, the Netherlands, Czech Republic, France (2x), Germany (2x), Croatia, Belgium, Latvia, Estonia, Ukraine and Denmark.

This system makes it possible to see a driver's improvement or decline from last year by comparing number with position.
