Portland Speedway was a half-mile race track located in Portland, Oregon. The track began as a five-eighths-mile (one km) clay oval in 1924 on the site of a field in north Portland. The track hosted big cars, midget cars, and stock cars before the suspension of racing during World War II. It was paved in 1946 as a half-mile oval. The 1988 Winston 200 was one of 36 NASCAR Winston West Series races held at the track.
