Colleville-Montgomery (French pronunciation: [kɔlvil mɔ̃ɡɔmʁi] ⓘ; formerly Colleville-sur-Orne) is a commune in the Calvados department in the Normandy region in northern France.

There are two neighbouring towns in Calvados called Sainte-Foy-de-Montgommery and Saint-Germain-de-Montgommery, but they are named for Montgomery's family ancestors.

The town was featured in the 1962 film, The Longest Day, detailing the French Resistance and their efforts on D-Day.

The windows were designed in the style of Gothic architecture and their stained glass were restored after World War II.

Built by the German army in 1942, it consists of a complex of bunkers which are being restored since 1990 by an association called "Les Amis du Suffolk Régiment".
