Champ Car World Series (CCWS) was the series sanctioned by Open-Wheel Racing Series Inc., a sanctioning body for American open-wheel car racing that operated from 2004 to 2008. It was the successor to Championship Auto Racing Teams (CART), which sanctioned open-wheel racing from 1979 until dissolving after the 2003 season.
