The 2004 British Grand Prix (formally the 2004 Formula 1 Foster's British Grand Prix) was a Formula One motor race held at the Silverstone Circuit on 11 July 2004.

The race was preceded by a demonstration of contemporary Formula One cars on Regent Street[3][4] in London, including former British Formula One World Champion Nigel Mansell driving the Jordan EJ14.

[6] The event was also notable for the death of Minardi Sporting Director John Walton, who died of a heart attack following the street demonstration, causing the Minardi team to withdraw its cars from Saturday's early practice session.

The bottom 6 teams in the 2003 Constructors' Championship were entitled to run a third car in free practice on Friday.

These drivers drove on Friday but did not compete in qualifying or the race.
