Stock car races in the now-NASCAR O'Reilly Auto Parts Series were held at Nazareth Speedway in Nazareth, Pennsylvania between 1988 to 2004, after the owners, International Speedway Corporation, closed the facility. The race was replaced with a race (currently known as Mission 200 at Watkins Glen) at Watkins Glen, another ISC-owned track.
After the closure of the track, the O'Reilly Series would return to racing in Pennsylvania when Pocono Raceway held its inaugural O'Reilly Series event, the Pocono Green 250 in 2016.
