The 2011 GP2 Asia Series was the fourth and final season of the GP2 Asia Series, and the second to be held entirely in a single calendar year. Rather than starting at the end of 2010 and running through the winter as with the previous two seasons of GP2 Asia, the 2011 season did not start until the beginning of February, to allow for the delivery of the brand new GP2/11 car to the teams and allow for testing before using it in the Asia Series. Previously the Asia Series had used the first generation GP2 car. The season also saw the début of three teams in the Series: two new teams, Carlin and Team Air Asia, as well as Racing Engineering, who had not competed in the Asia Series since its establishment.
The season was originally scheduled for six races to be held at three meetings, beginning on 11 February at the Yas Marina Circuit in the United Arab Emirates, and finishing on 13 March at the Bahrain International Circuit. However, both meetings due to be held in Bahrain, scheduled for 17–19 February and 11–13 March, were cancelled due to anti-government protests in the country's capital, Manama. On 1 March 2011, series organisers added a replacement final round of the Asia Series, to be held at the Autodromo Enzo e Dino Ferrari in Imola, Italy on 19–20 March.
Inaugural Asia Series champion Romain Grosjean of the DAMS team won the championship for the second time after title rival Jules Bianchi of Lotus ART was taken out of the final race by Super Nova Racing's Fairuz Fauzy. Giedo van der Garde finished third for the Barwa Addax Team, taking podiums in both races at Imola. As well as feature race victories apiece for Grosjean and Bianchi, sprint race victories were taken by Stefano Coletti of Trident Racing and Dani Clos of Racing Engineering. As well as Grosjean's drivers' championship win, DAMS also claimed the teams' championship by four points from Lotus ART.
