The 2001 CART PPG/Dayton Indy Lights Championship Powered By Buick consisted of 12 races. It was dominated by Townsend Bell who captured six victories on his way to the championship. It was the last Indy Lights season, as the series organizer, CART, decided to drop the Indy Lights series and concentrate its efforts on the Toyota Atlantic Championship. Most former Indy Lights teams that wished to stay in business went either to the Atlantic series, which replaced Indy Lights as the support race at most CART events, or the new Infiniti Pro Series, which ran in support of Indy Racing League events.
