Gueschart (French pronunciation: [ɡɛʃaʁ]; Picard: Djéchart) is a commune in the Somme department in Hauts-de-France in northern France. It was the target of bombing raids during the Second World War aimed at destroying nearby V1 launch sites, whose foundations can still be seen on the south-west outskirts of the village, near the D938.

Gueschart is situated on the D938 road, a mile from the banks of the river Authie, the border with the Pas-de-Calais, some 14 miles (23 km) northeast of Abbeville.
