The Place Stanislas is a large pedestrianised square in the French city of Nancy, in the Lorraine historic region.

The square and the surrounding buildings, unified by their colossal orders, were designed by the royal architect Emmanuel Héré de Corny (1705–1763).

[failed verification] Barthélémy Guibal and Paul-Louis Cyfflé created a bronze statue of Louis XV that was erected in the center of the square.

It has undergone several makeovers in its history and, in a low period of appreciation, served as a car parking area for nearly a quarter of a century, between 1958 and 1983.

The square is surrounded by an architecturally harmonious ensemble of buildings, most notably these: The Arc Héré, a triumphal arch built by Emmanuel Héré de Corny, stands in the centre of the fourth side, leading to the adjoining Place de la Carrière, where the main axis is developed as a double avenue of trees, with symmetrical buildings facing each other down its length.

The far end is defined by the hemi-cycles of colonnades that enclose the sides and are carried across the pre-existing façade of the Palais du Gouvernement.

The four corners and the west and east sides of the square feature gilded wrought iron gates and lanterns, created by Jean Lamour (1698–1771); who was also responsible for the wrought iron balustrade on the main staircase in the Hôtel de Ville, and the balcony across the centre of its main façade.
