As with many French surnames, Dupuyt likely originated as a family identifier tied to a particular landscape feature.

The name is relatively uncommon in contemporary records. It is most frequently found in France, with smaller concentrations in francophone communities in Belgium and Canada, and among diaspora populations in other countries.
