The 1977 Trans-Am Series was the twelfth running of the Sports Car Club of America's premier series. Porsche swept the season. All races except for the Six Hours of Watkins Glen ran for approximately one hundred miles. With the revival of the Can Am Series that year, 1977 also began a resurgence of interest in SCCA events. Trans Am would contribute with a slight resurgence in the eighties.
