The Buchloe–Memmingen railway is an approximately 45 kilometre long single-track, electrified mainline in the German state of Bavaria.

The formal groundbreaking ceremony took place in Memmingen on 23 March 2018—with the simultaneous start of construction work and a six-month line closure up to and including 14 November 2018.
