The 2009 Superleague Formula season was the second Superleague Formula championship. The series was rebranded the "Superleague Formula by Sonangol" for this season and also 2010 with the Angolan oil company becoming the title sponsor. It began on June 28 at Magny-Cours and finished on November 8 at Jarama.

Superleague Formula was an open wheel single seater motor racing formula, which started in 2008, at Donington Park in the United Kingdom. The league introduced team sponsorship by association football clubs. It used the slogan 'The Beautiful Race: Football at 300 km/h'. By 2011 the link with football was fading with more than half the teams no longer associated with football teams. It was founded by businessmen Alex Andreu and Robin Webb. On 19 May 2010, Andreu stepped down in his role as series president, with Alfredo Brisac named as his successor not many weeks later. The season ran between April and November at the same time as most other European race series. Every team used identical cars and 750-horsepower V-12 engines. The Sonangol Group was the series' title sponsor from June 2009 until the end of the 2010 season.
