Jürgen Barth (born December 10 1947 in Thum) is a German engineer and a former racecar driver. He is the son of Formula One driver and sports car racer Edgar Barth.

Barth started out as an engineer but became one of the most successful driver in sports car racing. He won the Le Mans 24 Hours in 1977 in a Porsche 936, with Jacky Ickx and Hurley Haywood, and in 1980 he won the 1000km Nürburgring with Rolf Stommelen.
