Merville (French pronunciation: [mɛʁvil] ⓘ; West Flemish: Mergem) is a commune in the Nord department and Hauts-de-France region of northern France.

The extensive buildings were briefly occupied by a community of religious sisters, and then became the Lille diocese's retreat and conference centre, a role in which it is still employed today.

Climate in this area has mild differences between highs and lows, and there is adequate rainfall year-round.

It forms part of the Merville commune, and is connected to the town by a regular bus service.

It has a small parish church dedicated to Notre Dame des Affligés (Our Lady of the Afflicted).
