The Porte de Vincennes [pɔʁt də vɛ̃.sɛn] is one of the city gates of Paris (France) situated in the Bel Air neighborhood of the 12th arrondissement.
The Porte de Vincennes is located where the northeast corner of the 12th arrondissement meets the southeast corner of the 20th arrondissement of Paris. The site is, more or less, delimited in the west by the Rue des Pyrénées and the Avenue du Docteur-Arnold-Netter; on the east, it is abutted by the Boulevard Davout and the Boulevard Soult. The road that actually passes through the 'porte' is the Cours de Vincennes, a major road that separates the two arrondissements.
