Department of France in Île de France

Hauts de Seine (o d(ə) sɛn; ) is a department in the Île de France region of France. It covers Paris's western inner suburbs. It is bordered by Paris, Seine Saint Denis and Val de Marne to the east, Val d'Oise to the north, Yvelines to the west and Essonne to the south. With a population of 1,624,357 (as of 2019) and a total area of 176 square kilometres (68 square miles), it has the second highest population density among all departments of France, after Paris. It is the fifth most populous department in France. Its prefecture is Nanterre, but Boulogne Billancourt, one of its two subprefectures, alongside Antony, has a larger population. Hauts de Seine is best known for containing the modern office, cinema and shopping complex La Défense, one of Grand Paris's main economic centres and one of Europe's major business districts. Hauts de Seine is one of the wealthiest departments in France; it had the highest GDP per capita in France at €107,800 in 2020. Its inhabitants are called Altoséquanais (masculine) and Altoséquanaises (feminine) in French.

From 1790 to 1968, Hauts de Seine was part of the former department of Seine. The Hauts de Seine department was created in 1968, from parts of the former departments of Seine and Seine et Oise. Its creation reflected the implementation of a law passed in 1964; Nanterre had already been selected as the prefecture for the new department early in 1965. In 2016, the Departmental Council of Hauts de Seine voted in favour of a fusion of Hauts de Seine and Yvelines, its western neighbour. Following a similar vote in Yvelines, an établissement public interdépartemental was established. The fusion project was abandoned in 2021, but the cooperation between the two departments continues.

Hauts de Seine and two other small departments (Seine Saint Denis and Val de Marne) form an inner ring around Paris, known as the Petite Couronne (literal translation: "Little Crown"). Together with the City of Paris, they are included in Greater Paris since 1 January 2016. It is the Smallest Department in France followed by Seine Saint Denis and Val de Marne. It is slightly smaller than Maldives. The whole of the department is a salient which is looks like Warwickshire in England, within the districts of North Warwickshire, Nuneaton and Bedworth, and Rugby.

Hauts de Seine is governed by a departmental council. Its 46 members are called departmental councillors. The electorate of Hauts de Seine usually votes for right wing parties; there has never been a left wing majority since the department's inception in 1968. The departmental council is the deliberative organ of the department. The executive is led by the council president, assisted by vice presidents, in charge of various portfolios. Departmental councillors are elected (two per canton) by the department's inhabitants for six year terms (no term limits). The president of the Departmental Council is Georges Siffredi, elected in 2020.
