Allan Simonsen (5 July 1978 – 22 June 2013) was a Danish racing driver, born in Odense. He died after a crash during the third lap of the 2013 24 Hours of Le Mans.
After beginning his career in karting racing against the likes of future Formula One World Champion Kimi Räikkönen, Simonsen moved to cars in 1999, winning the Danish Formula Ford Championship. He raced in Formula Palmer Audi in 2000, before moving to German Formula 3 and Formula Renault 2.0 UK in 2001.
Simonsen moved to sports car racing for 2002, driving a Ferrari 360 for Veloqx Motorsport in the British GT Championship. He began racing in Australia in 2003 for Mark Coffey Racing, driving a Ferrari 360 Challenge to 8th place in the 2003 Australian Nations Cup Championship for GT style cars and 2nd place in Group 2. He would then go on to finish in 8th place in the 2003 Bathurst 24 Hour driving a Lamborghini Diablo GTR. In the 2004 Australian Nations Cup Championship he drove the 360 to 3rd place in the Trophy Class while driving a Ferrari 550 GT2 in a limited campaign to 7th in the outright class.
While in Australia, Simonsen also drove in the Sandown 500 and Bathurst 1000 V8 Supercar events. Simonsen's best Bathurst result came in 2011, when he finished third for Kelly Racing driving alongside Greg Murphy in a Holden VE Commodore.
