The 1968 Trans-American Sedan Championship was the third running of the Sports Car Club of America's Trans-Am Series. 1968 marked the addition of the 12 Hours of Sebring and the 24 Hours of Daytona, the only year that the Trans-Am Series featured those races. The season marked the first time the series ever left the United States, as the race at Mont-Tremblant brought Trans-Am into Quebec. Chevrolet and Porsche won the manufacturers championships.
Championships
Points were awarded according to finishing position. Only the highest-placed car scored points for the manufacturer. Only the best 10 finishes counted towards the championship. Drivers' championships were not awarded in Trans-Am until 1972.
