2015 Moto2 World Championship
The 2015 FIM Moto2 World Championship was a part of the 67th F.I.M. Road Racing World Championship season. Marc VDS Racing Team rider Tito Rabat started the season as the defending riders' champion, having won his first championship title in 2014.

Rabat had been trailing by 78 points going to the Japanese Grand Prix. However, he had to withdraw from the event with a fractured left radius. Therefore, Johann Zarco became World Champion – the ninth different world champion in the intermediate class in as many years. Ajo Motorsport rider Zarco won eight races during the season – to become the most successful French rider in Grand Prix racing – and with a tally of 352 points, set a record points total for the intermediate class; surpassing Rabat's 346 from 2014. With Rabat missing three races due to injury, rookie Álex Rins (Pons Racing) moved ahead in the standings, and despite Rabat winning the final race in Valencia, Rins finished second to seal the runner-up spot by three points. Rins won two races at Indianapolis, and Phillip Island, while Rabat added his Valencia success to wins at Mugello and Motorland Aragón.

On one of the few non-Kalex motorcycles on the grid, Sam Lowes finished fourth in the championship for Speed Up, taking a race win at Circuit of the Americas, holding off Derendinger Racing Interwetten's Thomas Lüthi, who won at Le Mans. The season's only other race winners were Jonas Folger, who won at Losail and Jerez for the AGR Team, and Xavier Siméon, who took his first win for Gresini Racing at the Sachsenring. Kalex comfortably won the manufacturers' championship; they won 17 of the season's 18 races, with only Lowes' success at Circuit of the Americas stopping a clean sweep of victories. Speed Up finished second in the championship, with 209 points to Kalex's 445.

The 2015 season was the last year that Eni was the sole fuel supplier for Moto2, as Total became the championship's fuel supplier in 2016.
