Hailles () is a commune in the Somme department in Hauts-de-France in northern France.
Hailles is situated on the banks of the river Avre and by the D90e road, some southeast of Amiens.
The name probably comes from âÂÂhaieâ (eng: hedge), and has been variously written as Haies or Heilles. During the Franco-Prussian War of 1870, some francs-tireurs, hidden behind the town fired 60 times on a Prussian officer. All missed, he wasn't even scratched. The German troops threatened to burn down the town.
