The 2015 FIM Sidecarcross World Championship, the 36th edition of the competition, started on 6 April and finished after fifteen events on 20 September 2015.

[4] Van den Bogaart later rejoined the series at the seventh round, partnering Belgian rider Jan Hendrickx.

Second placed, 96 points behind, was French rider Valentin Giraud, who was partnered by compatriot Nicolas Musset for most of the season; however, Latvia's Elvijs Mucenieks partnered Giraud at the final three events of the season as Musset suffered a foot injury.

The Sidecarcross World Championship, first held in 1980 and organised by the Fédération Internationale de Motocyclisme, is an annual competition.

[1] Sidecarcross is similar to motocross except that the teams consist of two riders, a driver and a passenger.

Races are held on the same tracks as solo motocross but the handling of the machines differs as sidecars do not lean.

The majority of physical work in the sport is carried out by the passenger, who speeds up the sidecarcross in corners by leaning out.

While this overall winner received no extra world championship points, they usually were awarded a special trophy.

Above 32 entries, the starter field was sub-divided into two groups through ballot and the current standings.

The riders placed seventh and eighth remained in reserve should one of the qualified teams be unable to participate.
