Sant Jaume d'Enveja (Catalan pronunciation: [ˈsan ˈdʒawme ðamˈbejʒa]) municipality in the comarca of the Montsià in Catalonia, Spain.

It is linked to Amposta by a local road, and to Deltebre on the opposite bank by a service of barges.

This is due in part to the formation of the delta over the last few centuries from the river's sedimentary deposits.

The town's economy is centred on agriculture, principally rice cultivation, along with a strong tourist industry.

The tourism sector has seen an expansion in recent years based on the attractive countryside offered by the River Ebre Delta national park and its biodiversity.
