Saint-Denis is a town in the inner northern suburbs of Paris, which it borders on, the capital of an arrondissement in the Seine-Saint-Denis (93) department since 1993. It was once a sub-prefecture of the department of the Seine. The law of July 10, 1964 redistributed the former departments of Seine and Seine-et-Oise, which means that the town now belongs to Seine-Saint-Denis after an effective administrative transfer on January 1, 1968.

Saint-Denis borders the cities of Paris, Saint-Ouen-sur-Seine, Île-Saint-Denis, Épinay-sur-Seine, Villetaneuse, Pierrefitte-sur-Seine, Stains, La Courneuve and Aubervilliers. It is located in the Plaine de France. The southern part of the town, located between the Saint-Denis canal and Paris constitutes the Plaine Saint-Denis, which also extends over Aubervilliers and Saint-Ouen-sur-Seine.

The city is served by the A1 motorways (which connects it to Paris-Charles-de-Gaulle and Le Bourget airports) and A86, as well as by the Paris ring road. It is crossed by national roads 1, 14 and 186. The North motorway, built in the early 1960s, connects with the Porte de la Chapelle via avenue Wilson. Opened to traffic on December 17, 1965, this road divides the Plaine district in two until it was buried when the Stade de France was built.
