Molliens-Dreuil (French pronunciation: [mɔljɛ̃ dʁœj]) is a commune in the Somme department in Hauts-de-France in northern France.

The commune is situated on the D211 and D69 roads, some 13 miles (21 km) west of Amiens, in the valley of a small stream called the St.Landon.

By a decree of 19 September 1972, the two communes of Dreuil-lès-Molliens and Molliens-Vidame were combined into one, Molliens-Dreuil.
Molliens was first a commune in 1209 and was under the jurisdiction of the seigneurs of Picquigny from the twelfth century right up until the French Revolution, as was the neighbouring village of Dreuil.
