Hauts-de-Seine (; literally "Seine Heights") is a department of France. It is part of the Île-de-France region, and covers the western inner suburbs of Paris. It is small and densely populated and contains the modern office, theatre, and shopping complex known as La Défense.
The department of Hauts-de-Seine was created in 1968, from parts of the former départements of Seine and Seine-et-Oise. Its creation reflected the implementation of a law passed in 1964, and Nanterre had already been selected as the prefecture for the new department early in 1965.
In the 1990s and early 2000s, the Hauts-de-Seine received national attention as the result of a corruption scandal concerning the misuse of public funds provided for the department's housing projects. Implicated were former minister and former President of the general council of the Hauts-de-Seine, Charles Pasqua, and other personalities of the RPR party.
