Langhorne Speedway was a racetrack located in Langhorne, Pennsylvania. The 1-mile dirt track was unique because it had no straightaways, giving the track the appearance of a giant circle. The first race run at the facility was a National Championship Stock Car Circuit (a forerunner to NASCAR) race in 1947, with Bob Flock taking home the checkered flag.

From 1947 to 1957, it became an annual race on the Fledging NASCAR schedule, with the following drivers who won those Langhorne races, Al Keller, Curtis Turner, Fonty Flock, Herb Thomas, Dick Rathmann, Tim Flock, Buck Baker, Paul Goldsmith, and Fireball Roberts. The track hosted USAC races. The track was paved in 1965. USAC ran open-wheel races there from 1956 to 1970 which were won by such famous names as A.J. Foyt, Mario Andretti, Bobby Unser, Gordon Johncock, and Eddie Sachs.

Sadly, the track became known as one of the more dangerous tracks in the motorsports circle. Larry Mann. Frank Arford, John McVitty, and Jimmy Bryan were all killed racing at this track. It is now no longer in existence.
