Marckolsheim (French pronunciation: [maʁkɔlsaim]; German: Markolsheim) is a commune in the Bas-Rhin department in Alsace in north-eastern France.
On the eastern edge of the town the Casemate de Marckolsheim Sud, a Maginot Line fortification left over from the Second World War, has been converted into a small museum. Approximately 3 kilometres to the east the Rhine has been dammed and a hydro-electric power station installed.
