It is part of the L'Île-d'Orléans Regional County Municipality, on the southeastern side of Île d'Orléans.

[1] Although having a well-established agricultural history, Saint-Jean's location on the Saint Lawrence River prompted also development of maritime and fishing trades.

It was especially known for its river pilots who would guide vessels through the treacherous Saint Lawrence navigation channel.

[1] Like the neighbouring municipalities, Saint-Jean has a rich cultural heritage with many historic buildings.

Just past the heart of the village, there is a long line of quaint houses (formerly belonging to river pilots), art galleries, and artists' studios.
