2006 Indy Pro Series season

The 2006 Indy Racing League Indy Pro Series was the fifth season of the developmental open-wheel racing series. It was the first season to include double-header races on road and street courses. The season began at the Homestead-Miami Speedway on March 26 and finished September 9 at Chicagoland Speedway.

English rookie Jay Howard, driving for Sam Schmidt Motorsports narrowly won the championship by four points over American rookie Jonathan Klein of Andretti Green Racing. Defending series champion Wade Cunningham, driving for Brian Stewart Racing, finished third in points despite missing two races due to illness and scored more points per race than Howard or Klein. Rookie Alex Lloyd won two races, but missed three due to funding issues and finished seventh in points. Brazilian rookie Raphael Matos swept the race weekend at St. Petersburg, his first two series starts. Graham Rahal made his only Indy Pro Series start at the Liberty Challenge and won the pole and nearly won the race.

41 different drivers competed in a race but only six started all twelve races.
