Falaise (French pronunciation: [falɛz] ) is a commune in the Calvados department in the Normandy region in northwestern France.

Flowing through Falaise are the river Ante and the river Trainefeuille, both tributaries of the river Dives.

Falaise borders the area known as Suisse Normande, on its eastern side.

The area around Falaise has been inhabited from prehistoric times, but it was only at the end of the prehistoric period and the beginning of the Gallo-Roman era that the area, Falaise in particular, was regularly inhabited. Evidence of settlement from the time has been found at Vaston, an agricultural area just north-east of the modern town.

Falaise, as it is sited today, probably came into being around the castle.

The town was the birthplace of William the Conqueror, first of the Norman kings of England. He was frequently referred to as William the Bastard, on account of his being born out of wedlock to Herleva from Falaise, reputedly a tanner's daughter.

The Château de Falaise (12th–13th century), which overlooks the town from a high crag (French: falaise), was formerly the seat of the Dukes of Normandy. Also, the Treaty of Falaise was signed at the castle in December 1174 between the captive William I, King of Scots, and the Plantagenet king of England, Henry II.

The town was also the place that Rabbi Yom Tov of Falaise, grandchild of Rashi, held his rabbinical court.

On 26 October 1851, a statue of William the Conqueror was inaugurated here (at his place of birth).

In modern times, it is known for the battle of the Falaise Pocket during the Allied reconquest of France (called Operation Overlord) in August 1944 in which two German armies were encircled and destroyed by the allied armies. Some 10,000 German troops were killed and 50,000 taken prisoner.

Two-thirds of Falaise was destroyed by allied bombing before the town was taken by a combined force of Canadian and Polish troops. Falaise was largely restored after the war.
