Le Houlme (French pronunciation: [lə ulm]) is a commune in the Seine-Maritime department in the Normandy region in northern France.

A small light industrial and farming town situated by the banks of the river Cailly, some 7 miles (11 km) northwest of the centre of Rouen at the junction of the D51, D90 and the D927 roads. SNCF operates a TER service here. The town is located in a place where the Cailly's valley is beginning to narrow. Thus, the town extends from the Cailly's valley to the beginning of the plateau of Normandy, with some housings located on the cliffs leading to the plateau itself.
