'Milan I' was an Allied unrealised operation for an airborne landing behind the 'Westwall' in the area of Trier in western Germany (September 1944).

The operation would have been based on the use of Major General Matthew B. Ridgway’s US XVIII Airborne Corps of Lieutenant General Lewis H. Brereton’s Allied 1^st Airborne Army to effect a landing and was designed to facilitate the penetration of Lieutenant General George S. Patton’s US 3^rd Army through the 'Westwall'.
