The 2001 American Le Mans Series season was the third season for the IMSA American Le Mans Series, and the 31st overall season of the IMSA GT Championship. It was a series for Le Mans Prototypes (LMP) and Grand Touring (GT) race cars divided into 4 classes: LMP900, LMP675, GTS, and GT. It began March 4, 2001 and ended October 6, 2001 after 10 races.
This season shared events with the new European Le Mans Series, with two events being held in Europe.
The schedule for the 2001 featured the only time in ALMS history that the opening event was not the 12 Hours of Sebring, instead being preceded by the Grand Prix of Texas. After Sebring, the two ELMS rounds at Donington Park and Jarama were optional for ALMS teams as the next North American event was not until after Le Mans. The Mid-Ohio Sports Car Course was added to the schedule, replacing previous races at Las Vegas Motor Speedway and Charlotte Motor Speedway. This was the last season to feature events held on road courses at oval circuits.
