The Red Bull RB9 is a Formula One racing car designed by Adrian Newey for Red Bull Racing to compete in the 2013 Formula One season.{{cite news|title=Red Bull's Adrian Newey says title wins affecting 2013 preparation|url=https://www.bbc.co.uk/sport/0/formula1/20898956|first=Andrew|last=Benson|work=BBC F1|publisher=BBC|date=3 January 2013|access-date=4 January 2013|quote=[Designer Adrian Newey] said that the challenge of running dual programmes and the necessity to keep developing the 2012 car to the end of the season had delayed work on the 2013 car, the RB9.}}{{cite news|title=Red Bull win third constructors' title in a row|url=http://www.f1fanatic.co.uk/2012/11/18/red-bull-clinch-constructors-title-victory-row/|first=Keith|last=Collantine|work=F1 Fanatic|publisher=Keith Collantine|date=18 November 2012|access-date=7 January 2013}} The car was driven by (then) three-time World Drivers' Champion Sebastian Vettel and teammate Mark Webber. Sebastian Vettel, in keeping with his tradition of naming his cars, named his RB9 "Hungry Heidi," after German model Heidi Klum.{{cite news|title=F1 News - Vettel names RB9 Hungry Heidi|url=http://www.sportpulse.net/content/f1-news-vettel-names-rb9-hungry-heidi-7402|first=Dessislava|last=Jeleva|work=SportPulse|publisher=Dessislava Jeleva|date=14 March 2013|access-date=8 June 2013|archive-date=13 October 2013|archive-url=https://web.archive.org/web/20131013230329/http://www.sportpulse.net/content/f1-news-vettel-names-rb9-hungry-heidi-7402|url-status=dead}} Vettel would ultimately claim the Drivers' Championship title, for the fourth consecutive season, at the {{F1 GP|2013|Indian}}, after ten wins during the season. Vettel and Webber also brought the car to the last win and world titles for a V8 and a naturally-aspirated engine-powered F1 car, marking the end of the V8 and the naturally-aspirated engine-era of Formula One which began in 1989 when turbocharged engines were banned at that time.

As of {{F1|2024}}, the Red Bull RB9 was the most recent Renault-powered Formula One car to win the Constructors' Championship.
