The 2014 Japanese Grand Prix was a Formula One motor race held on 5 October 2014 at the Suzuka Circuit in Suzuka, Mie. It was the 15th race of the 2014 FIA Formula One World Championship.

Mercedes driver Lewis Hamilton won the race starting from second position. His teammate, Nico Rosberg, finished second and Red Bull Racing driver Sebastian Vettel was third. It was Hamilton's eighth victory of the season and the 30th of his Formula One career.

The race was scheduled to run for 53 laps, but was brought to an end on the 46th lap (with the result taken at the end of lap 44) after an accident involving Jules Bianchi. Bianchi lost control of his Marussia at the Dunlop Curve on the 43rd lap and collided with a tractor crane that was tending to Adrian Sutil's Sauber, which had spun off on the previous lap. Bianchi sustained severe head injuries in the accident, from which he died in France on 17 July 2015, thus becoming the first driver to die as a result of injuries sustained in a Formula One race since Ayrton Senna in 1994. The accident prompted Formula One's governing body, the Fédération Internationale de l'Automobile (FIA), to investigate the incident with a ten-person panel in which it was determined there was no single cause that prompted the crash. The investigation led to the virtual safety car(VSC) being introduced from the 2015 season onwards.
