Sucé-sur-Erdre (French pronunciation: [syse syʁ ɛʁdʁ] ⓘ, literally Sucé on Erdre; Breton: Sulieg) is a commune in the Loire-Atlantique department in western France.

The town was fairly small (2,000 or so) for quite some time until it began to be absorbed into the greater suburbia of Nantes.

In general, the area is middle-class with a good portion of upper-middle class and upper-class homes, especially on the river banks.

Sucé-sur-Erdre has had few encounters with history, its greatest claim to fame being that the famous philosopher René Descartes spent some time there (although this is not very well documented).

There are many picturesque farm houses in the area, although they are disappearing quickly due to the accelerated modernization brought by the expansion of Nantes.
