Peasant Family in an Interior is a large oil painting executed c.1642 by one or more of the French Le Nain brothers, Louis or Antoine.

Because of the similarity of their styles of painting and the fact that they signed their paintings only with their surnames they are commonly referred to collectively as Le Nain.

This particular genre painting depicts three generations of a peasant family relaxing by the fireside round a table in the evening.

Light coming from a window illuminates their faces and the folds of their simple clothes.

By virtue of its size, quality and character it is considered one of the Le Nain's masterpieces.
