The 2011 Intercontinental Le Mans Cup was the second and final Season running of the Automobile Club de l'Ouest's (ACO) Intercontinental Le Mans Cup, an international auto racing championship for manufacturers and teams.

Note that for each individual races, cars not competing in the Intercontinental Cup may have won their respective class.

The pole-sitter bonus was retained, with a single point being awarded for qualifying fastest in class for each event.

Engines were tightly controlled by the organizers, and their running time was tracked (including practice, qualifying, and race hours).

For engines which accumulated 15 or more hours by the end of a race, the entrant would receive a bonus point.

[2] Peugeot and Audi returned to the competition competing for the premier title of LMP1 manufacturer, both bringing new cars.

Audi was unable to use their new R18 in the first event, and while the new car would be quick enough to win the pole at two events and pick up the make's only win of the season at the prestigious 24 Hours of Le Mans, it would ultimately prove unable to pace the Peugeots over the balance of the season and Audi was not able to be competitive in the standings as a result.

Audi's Joest team was able to briefly take the lead in the standings after their victory at the 24 Hours of Le Mans, which netted double points, but the Peugeot Sport Total team would run the table for the rest of the season, not only winning every race, but even gathering the pole-sitter bonus points for each one as well.

Aston Martin's new AMR-One car proved to be a failure, and the team's late-season return with the Lola B09/60 was too late to make an impact.

The LMP2 cup was essentially a battle between Signatech and OAK Racing, with Level 5 Motorsports failing to compete season-long.
