Igny (pronounced [iɲi]) is a French commune situated in the département de l'Essonne in the Île-de-France region. From the fortified farm of Amblainvilliers in the 13th century, through the estates dependent on Vilgénis, belonging to the families de Vigny and then de Bourbon-Condé, Igny has, after having been an important strawberry-producing site in the 19th century and having benefited from numerous successive housing developments in the 20th century, become a residential commune in the outer suburbs of Paris, combining areas of woodland, a town centre with an old rural charm, and recent detached housing estates.
