Poissy (French: [pwasi] ) is a commune in the Yvelines department in the Île-de-France region in north-central France. It is located in the western suburbs of Paris, 23.8 km (14.8 mi) from the centre of Paris. Inhabitants are called Pisciacais in French.

Poissy is one of the oldest royal cities of Île-de-France, birthplace of Louis IX of France and Philip III of France, before being supplanted from the 15th century by Saint-Germain-en-Laye. In 1561, it was the site of a fruitless CatholicHuguenot conference, the Colloquy of Poissy.

The area is known for hosting the Automobiles Gregoire successively, Matford, Ford SAF, Simca, Chrysler, Talbot factories and now hosts one of France's largest Peugeot factories. The "Simca Poissy engine" was made there.

Poissy is the 165th most populated city in Metropolitan France.
