Port Royal Speedway is a 0.5-mile (0.80 km) dirt racetrack in Port Royal, Juniata County, Pennsylvania in the United States.

Like all of the tracks in the United States, it closed during the World War II years (1941–1945) and re-opened in 1946.

Port Royal Speedway hosts a weekly schedule of local Sprint Car, Late Model, and Pro-Stock dirt track racing, and is nicknamed "The Speed Palace".

Several national touring series organizations visit the track during the racing season, including the World of Outlaws Late Model Series[1] and the All Star Circuit of Champions.
