The 2009 Hungarian Grand Prix (officially known as the Formula 1 ING Magyar Nagydíj 2009) was a Formula One motor race held on 26 July 2009 at the Hungaroring in Mogyoród, north of Budapest, Hungary. It was the tenth race of the 2009 Formula One season. The 70-lap race was won by world champion Lewis Hamilton for McLaren-Mercedes, after starting from fourth place on the grid. The world champion Kimi Räikkönen finished second for Ferrari, with Red Bull Racing's Mark Webber finishing third. Championship leader Jenson Button had a poor race to finish seventh, losing ground to Webber in the championship.

He replaced the fired Sébastien Bourdais at Scuderia Toro Rosso.

Vettel's teammate Mark Webber, who signed a new one-year contract before the race weekend, was 1.5 points behind Vettel and an equal number ahead of Button's teammate Rubens Barrichello. Brawn GP also held the lead in the Constructors' Championship, with a lead of 19.5 points from a resurgent Red Bull Racing, who were a further 48 points clear of Toyota. Toyota held an advantage of only 1.5 points over defending champions Scuderia Ferrari. Webber won the previous race in Germany from pole position, to claim his first win at the 130th attempt. Despite an early drive-through penalty assessed for a dangerous manoeuvre to keep the Brawn GP car of Barrichello behind him at the start, the Australian driver had enough time in hand to rejoin out front and win by nearly
