Rennbahn Dortmund, Horse racing venue and architectural heritage monument in Dortmund, Germany.

Rennbahn Dortmund is a horse racing facility featuring an oval track, spectator grandstands, and support buildings for training and stabling competition horses. The structures showcase architectural elements that are protected as heritage monuments, reflecting the region's built history.

The first Dortmund racecourse was laid out in 1893 by the von Romberg family at the Buschmühle, south of today's Westfalenpark, and was lost to the expansion of the Phoenix-West ironworks. The present track opened in Wambel on 3 July 1913, built to plans by the Cologne firm Stein und Ziedorn with grandstands, stables and service buildings partly in half-timbered style; more stands followed in the 1920s. In 1981 a floodlit sand track made it Europe's first all-weather racecourse.

The racecourse hosts the Deutsche St. Leger and the Große Preis der Dortmunder Wirtschaft each year. Its grandstands, some in half-timbered style, date from the 1913 opening and the 1920s, and are listed as a monument. The infield holds a 9-hole golf course.

Check the race schedule before visiting, as the facility is accessible mainly during scheduled events. The grounds are accessible by public transportation and offer parking options plus dining facilities on site.
