The 1972 World Championship for Makes and International Grand Touring Trophy seasons were the 20th season of the FIA World Sportscar Championship.
It ran from 9 January 1972 to 22 July 1972, and was composed of 11 races.
Points were awarded to the top 10 finishers in the order of 20-15-12-10-8-6-4-3-2-1.
Group 5 Sports Cars and Group 4 Grand Touring Cars were awarded points for the overall championship, but the GT class also had their own separate award.
Cars participating in races that were not included in the Sports or GT classes (such as Group 2 Touring Cars) were skipped when awarding points for the overall championship.
