Blainville-sur-Orne is a commune in the Calvados department in the Basse-Normandie region in northwestern France.
Blainville-sur-Orne is on the west side of the Canal de Caen à la Mer, just south of Bénouville and the famous Pegasus Bridge of D-Day fame. The town is also home to a Renault Trucks (formerly Saviem) manufacturing plant. The plant is across the canal to the southeast, between the canal and the Orne River. Just across the river from the plant is the commune of Colombelles. Directly across the canal from Blainville-sur-Orne is the fourth commercial French port for the importation of exotic wood, generally coming from the Gulf of Guinea. The port also exports cereals that are produced in the area and has a silo capacity of 33,000 tons.
