The 2013 American Le Mans Series was the fifteenth and final season of the International Motor Sports Association GT Championship being labeled as the American Le Mans Series, before merging up with the Grand-Am Rolex Sports Car Series in 2014.
As the IMSA and Grand-Am merger was announced on September 5, 2012, between NASCAR Holdings (Grand-Am's owner) and Panoz Motorsports, the 2013 season was the transition season as both series were now held under the NASCAR Holdings banner. As such, this is the 43rd season of the series dating back to the 1971 IMSA GT Championship.
It began on March 16 with the 61st running of the 12 Hours of Sebring and ended with the 16th running of the Petit Le Mans on October 19. At the seventh round in Baltimore, Muscle Milk Pickett Racing successfully defended their 2012 Prototype One championship.
Calendar The calendar was announced October 18, 2012. The race at the Circuit of the Americas near Austin, Texas, was previously announced in June 2012, and a combined event with the Rolex Sports Car Series at Road America was announced on September 28, 2012. The event at Mid-Ohio, a joint weekend with the IndyCar Series, was not renewed. The event at Mazda Raceway Laguna Seca was initially scheduled on May 18. However, with this date conflicting with the 24 Hours Nürburgring, the series opted to move the event up one week to May 11. The event was also shortened from 6 hours to 4 hours.

Team announcements On September 17, 2012, it was announced that the DeltaWing prototype had been cleared for entry into the ALMS for 2013. On October 26, 2012, Porsche announced that it would cease development of the 911 GT3-RSR (Type 997), which had competed in the series since 2005, to focus its efforts on developing its next generation 911 GT3-RSR (Type 991) race car set to debut in 2014. As a result, the development partnership with Flying Lizard Motorsports was discontinued. Porsche will, however, continue to provide support for customer teams continuing to compete with the 911 GT3-RSR (Type 997). On November 15, 2012, Flying Lizard Motorsports announced that they would transition to competing in the GT Challenge category. On that date they confirmed a full-season campaign for their #44 Porsche 911 GT3 Cup entry to be piloted by team principal Seth Neiman and 2-time 24 Hours of Daytona GT class champion Spencer Pumpelly.

Braun and Bennett will be joined by Mark Wilkins for the 12 Hours of Sebring and Petit Le Mans. The driver lineup for the team's second entry (No. 06) is still pending. On December 19, 2012 Paul Miller Racing announced that Porsche works driver, Marco Holzer, would join Bryce Miller in competing for the GT championship in the team's 911 GT3-RSR (Type 997).

They will field one Ferrari 458 Italia, with drivers yet to be announced. On January 22, 2013, CORE Autosport announced that it would field a Porsche 997 GT3-RSR in GT, in addition to their PC effort. Patrick Long and Tom Kimber-Smith will drive it.
