Circuit Paul Armagnac is a motorsport race track near Nogaro in southwestern France. The track was built in 1960. The venue hosted the French round of the Grand Prix motorcycle road racing world championship in 1978 and 1982, as well as the 2003 round of the FIA Sportscar Championship. It also hosted rounds of the Formula 3000 series between 1990 and 1993. The Formula Three Euro Series also visits the circuit. The FIA GT Championship also visits the circuit with the latest event being the Nogaro 2 Hours held on 1 April 2013.
The circuit was used for many years by the Eco-marathon competition in which teams of students from schools and universities run self-developed energy efficient vehicles aiming to cover the longest distance using the least fuel. This competition later moved to Germany's Lausitzring and from 2012 is run on a street circuit in Rotterdam.
