Delmenhorst – Wesermarsch – Oldenburg-Land is located in northwestern Lower Saxony. As of the 2021 federal election, it comprises the independent city of Delmenhorst and the entirety of the districts of Wesermarsch and Landkreis Oldenburg.^[1]

Delmenhorst – Wesermarsch – Oldenburg-Land was created in 1949. In the 1949 election, it was Lower Saxony constituency 7. For the 1953 through 1961 elections, it was constituency 29 in the numbering system. From 1965 through 1998, it was constituency 23; from 2002 through 2009, it was constituency 29. Since the 2013 election, it has been constituency 28.

Originally, it comprised the city of Oldenburg, the district of Wesermarsch, and the municipalities of Dötlingen, Ganderkesee, Hasbergen, Hude, Schönemoor, Stuhr and Wildeshausen from Landkreis Oldenburg. At this time, it was named Delmenhorst – Wesermarsch. Due to administrative reforms, in the 1976 election, it gained the former municipality of Wüsting. In the 1980 election, the constituency gained the entirety of Landkreis Oldenburg. In the 1987 election, it was renamed to Delmenhorst – Wesermarsch – Oldenburg-Land.

The constituency was held by the Social Democratic Party (SPD) from its creation in 1949 until 1953, during which time it was represented by Fritz Ohlig. It was won by the Christian Democratic Union (CDU) in 1957, and represented by Hermann Ehlers (until 1957) and then J. Hermann Siemer. In 1961, it was won by the SPD candidate Heinrich Müller, who served for one term. Siemer won the constituency back for the CDU in the following election, but Müller returned again in 1969 and served three terms. He was succeeded in 1980 by fellow SPD candidate Margitta Terborg, who served until 1998. Holger Ortel then held the constituency for the SPD until 2009. CDU candidate Astrid Grotelüschen won in 2009, and was re-elected in 2013 and 2017. Susanne Mittag regained it for the SPD in 2021.
