Daniel Clive Wheldon (22 June 1978 – 16 October 2011) was a British motor racing driver who won the 2005 IndyCar Series for Andretti Green Racing (AGR). He won the Indianapolis 500 in 2005 and 2011, and was co-winner of the 2006 24 Hours of Daytona with Chip Ganassi Racing (CGR).
Wheldon began competitive karting at the age of eight and achieved early success, before progressing to open-wheel car racing in the U.S. F2000 National Championship, the Toyota Atlantic Championship and Indy Lights. He began driving in IndyCar with Panther Racing in 2002. The following year, Wheldon moved to AGR, finishing as runner-up in the 2004 championship. He won the drivers' title in 2005 with the record for most victories (including that year's Indianapolis 500) during a season. In the 2006 season, he moved to CGR, tying Sam Hornish Jr. in points but finishing second because of count-back on the number of victories taken by both drivers.
