Serqueux (French pronunciation: [sɛʁkø]) is a commune in the Seine-Maritime department in the Normandy region in northern France.

A village situated at the source of the Epte river in the Pays de Bray, some 30 miles (48 km) southeast of Dieppe at the junction of the D 1314, D 13 and D 83 roads.

Serqueux has an important plant producing most of the gum arabic in the world.

First mentioned as "Sarkeus" in the twelfth century, the name derives from the Greek sarkofagos, owing to the large Merovingian necropolis in the commune.

Much of the village including the church, was destroyed by Allied bombing during World War II.
