Southern Oregon Speedway, Race track in the United States

Southern Oregon Speedway is a 3/8-mile banked dirt oval at the Jackson County Sports Park near White City, Oregon. The park also holds a shooting range, a dragstrip and a go-kart track. Weekly racing runs from April through October, weather permitting, in Mini Stock, Super 4, Pro Stock, Dwarf and Modified classes.

Southern Oregon Speedway opened in 1996, after the historic Medford Speedway at the Jackson County Posse Grounds closed in 1989. It was built to carry on grassroots dirt racing at the Jackson County Sports Park. In 2021 the track went inactive amid lease complications and operational challenges, then sat dormant and partly abandoned until new management revived it in 2024.

The NARC 410 King of the West Sprint Car Series has raced here since 2022, opening a speed week billed as "The Fastest Five Days in Motorsports" as its first event. Weekly cards from April through October run Mini Stock, Super 4, Pro Stock, Dwarf and Modified classes, while 360 Sprint, 410 Sprint and Late Model cars appear only irregularly.

The speedway sits within the Jackson County Sports Park near White City, sharing the grounds with a shooting range, a dragstrip and a go-kart track. Racing runs weekly from April through October, weather permitting, so check conditions before travelling. The 3/8-mile banked dirt oval hosts Mini Stock, Super 4, Pro Stock, Dwarf and Modified classes.

Adjacent to the main oval are smaller tracks for Go-Karts and Micro Sprints where young and new drivers develop early skills on dirt. Many of the top drivers on the main circuit began their racing careers on these smaller courses.
