The Grande Île (French pronunciation: [ɡʁɑ̃d il]; German: Große Insel) is an island that lies at the historic centre of the city of Strasbourg in France.

[1] At the time, the International Council on Monuments and Sites noted that the Grande Île is "an old quarter that exemplifies medieval cities".

At the western end of the island is the quarter of Petite France, the former home of the city's tanners, millers and fishermen, and now one of Strasbourg's main tourist attractions.

Besides the cathedral, the Grande Île is home to four other centuries-old churches: St. Thomas, St. Pierre-le-Vieux, St. Pierre-le-Jeune, and St. Étienne.

[3] To mark the Grande Île's status as a World Heritage Site, 22 brass plates were placed on the bridges giving access to the island.
