Seine-Saint-Denis (French pronunciation: ​[sɛnsɛ̃dəni]) is a French department located in the Île-de-France region. Locally, it is often referred to colloquially as quatre-vingt treize or neuf trois (i.e. "ninety-three" or "nine three"), after its official administrative number, 93.

The learned and rarely used demonym for the inhabitants is Séquano-Dionysiens; more common is Dionysiens.

Seine-Saint-Denis is located to the northeast of Paris. It has a surface area of only 236 km², making it one of the smallest departments in France. Seine-Saint-Denis and two other small departments, Hauts-de-Seine and Val-de-Marne, form a ring around Paris, known as the Petite Couronne ("little crown"). They form, together with Paris the Greater Paris since January 1st 2016.

Seine-Saint-Denis is made up of three departmental arrondissements and 40 communes:

Seine-Saint-Denis was created in January 1968, through the implementation of a law passed in July 1964. It was formed from the part of the (hitherto larger) Seine department to the north and north-east of the Paris ring road (and the line of the old city walls), together with a small slice taken from Seine-et-Oise.
