The tunnel de l'Étoile is a road tunnel in Paris. It links the avenue des Champs-Élysées to the avenue de la Grande Armée, passing underneath the place Charles-de-Gaulle and the Arc de Triomphe. It is around 400 metres long and has two one way lanes.
Its entrance has been the site of many road traffic accidents by lorries. In effect the tunnel has a height of 2.4 metres, which is only signalled by a sign hanging above the entrance. Lorries are too high and hit the tunnel roof. No portico can be built on the surface since it would affect the appearance of the Arc de Triomphe and breach the Arc's listing statute. In 2009 an accident occurred there every two weeks.
