The 2009 Indy Racing League Firestone Indy Lights season began April 4 in St. Petersburg, Florida, where it ran a double-header weekend in support to the season-opening IndyCar Series event.

Unlike the 2008 season, the St. Petersburg weekend will be the only double-header the series has announced.

J. R. Hildebrand ended the season as champion for Andretti Green-AFS Racing, winning the championship by nearly 100 points ahead of Vision Racing's James Davison and his AGR-AFS Racing team-mate Sebastián Saavedra.

All drivers compete in Firestone-shod Dallaras.

The season consisted of fifteen races, including a mix of ovals, temporary street circuits and road courses.
