The 2011 Bahrain Grand Prix was scheduled to be the opening round of the 2011 Formula One World Championship. Planned to be held on 13 March 2011 at the Bahrain International Circuit in Sakhir, Bahrain, it was postponed on 21 February 2011 due to civil unrest. On 3 June, it was announced that the race would be held on 30 October, which would have made it the 17th of 20 Grands Prix held during 2011. Following controversy over the reinstatement of the race, organisers of the Grand Prix abandoned their bid to host a race in 2011. The race would return in 2012 amidst the conflict; the decision to run the race would be met with heavy controversy and numerous protests from civilians and major diplomatic figures alike.

The 2011 FIA Formula One World Championship was the 65th season of FIA Formula One motor racing. The original calendar for the 2011 Formula One World Championship consisted of twenty rounds, including the inaugural running of the Indian Grand Prix before the cancellation of the Bahrain Grand Prix. Pirelli returned to the sport as tyre supplier for all teams, taking over from Bridgestone, marking their return to Formula One for the first time since the 1991 season. Red Bull Racing was the reigning Constructors' Champion. Red Bull Racing's Sebastian Vettel was the defending Drivers' Champion, one of five World Champions appearing on the grid. Vettel won his second World Championship at the 2011 Japanese Grand Prix, becoming the youngest driver, at 24 years and 98 days, to do so. Red Bull Racing won the Constructors' Championship.
