The United States Road Racing Championship (USRRC) was one of two sports car racing series.
The United States Road Racing Championship (USRRC) was created by the SCCA in 1962. It was the first SCCA series for professional racing drivers.
The USRRC ran from 1963 until 1968 when it was abandoned in favor of the more successful Can-Am series, which was also run by the SCCA.
In 1998 the United States Road Racing Championship (USRRC) name was revived as an alternative to the IMSA GT Championship, as well as reviving the Can-Am name for its top class. For 1999 the series reached an agreement with the International Sports Racing Series in Europe, in which the two series would share the same rules for prototypes.
At the end of 1999 the series was taken over by the new Grand American Road Racing Association (GARRA), and the championship was reborn as the Grand American Road Racing Championship, now known as the Rolex Sports Car Series.
