Longueval (French pronunciation: [lɔ̃ɡval]) is a commune in the Somme department in Hauts-de-France in northern France.

Longueval is located 38 km (24 mi) northwest of Amiens on the D919 road, at the junction with the D8.

Longueval is found in the north-east of the département, almost equidistant to the surrounding towns of Péronne (to the east), Albert (west) and Bapaume (north).

The village was almost completely destroyed during World War I. Caterpillar Valley Cemetery is located outside Longueval, on the road to Bazentin.

In the centre of the village is the Pipers' Memorial, built to commemorate bagpipers who fought in the First World War.
