The 2014 Valencian Community motorcycle Grand Prix was the eighteenth and last round of the 2014 Grand Prix motorcycle racing season. It was held at the Circuit Ricardo Tormo in Valencia on 9 November 2014.
In the MotoGP class, Valentino Rossi took his first pole position since the 2010 French Grand Prix. However, it was Marc Márquez who won the race, taking his thirteenth victory of the season, surpassing the previous premier class record of twelve wins set by Mick Doohan in 1997. Rossi crossed the line in second place to take the runner-up spot in the championship, while the podium was completed by Dani Pedrosa. Further down the order, Jorge Lorenzo and Andrea Iannone took the decision to swap bikes – on lap 20 – as light rain fell. Both riders struggled to get the bike stopped in the uncertain conditions and dropped down the order; Iannone finished 22nd, while Lorenzo retired from the race. The Suzuki MotoGP team returned to the series in a wildcard appearance, ahead of a full-season entry in 2015. Utilising the new Suzuki GSX-RR, Randy de Puniet retired from the race before the halfway mark. Drive M7 Aspar rider, Hiroshi Aoyama, rode an Open-specification Honda RC213V-RS and finished in fifteenth place.
In the Moto2 race, Thomas Lüthi took his second victory of the season, after capitalising on a mistake by the world champion, Esteve Rabat, on the final lap to take the spoils. Rabat had been leading the race before missing a gear coming out of the final corner, and Lüthi was able to prevail by 0.133 seconds at the line. Rabat's second place did however, seal a record number of points scored for an intermediate class season. Johann Zarco completed the podium in third place, his fourth podium of the season. Aside from the race honours, the runner-up position in the final championship standings was decided by virtue of a collision between the two competitors battling for the position. Rabat's team-mate Mika Kallio and Maverick Viñales both retired from the race, thus giving Kallio the position by 15 points.
The world title was decided in the final Moto3 race of the season, with a third-place finish for Álex Márquez enough to give him his first world title by two points, despite his title rival Jack Miller winning the race. In the process, he and his brother Marc Márquez became the first brothers to win world motorcycle racing titles. Splitting the title rivals in the finishing order was Isaac Viñales, taking his third podium of the season.
