Domart-en-Ponthieu (French pronunciation: [dɔmaʁ ɑ̃ pɔ̃tjø], literally Domart in Ponthieu; Picard: Donmart-in-Pontiu) is a commune in the Somme department in Hauts-de-France in northern France.

The commune is situated on the D216 road, some 14 miles (23 km) southeast of Abbeville.

After the Armistice following World War I, British troops from the Oxfordshire and Buckinghamshire Light Infantry were stationed at Domart-en-Ponthieu under the command of a Colonel Flanagan. Awaiting demobilisation, they were able to relax for a time. Private Arthur Bullock recalled this stay, including a memorable occasion on which he heard a talk by the renowned Woodbine Willie.
