Berlin-Steglitz-Zehlendorf

Berlin-Steglitz-Zehlendorf is an electoral constituency in southwestern Berlin, represented in the Bundestag since 1990. It elects one member through a first-past-the-post system and is currently designated as constituency number 78. The constituency was established after German reunification in 1990 and has undergone several boundary changes over the years.

Initially, it comprised parts of Steglitz and Zehlendorf boroughs, excluding areas east of the Teltow Canal. By 2002, following a merger of the boroughs, it became coterminous with the Steglitz-Zehlendorf borough. The constituency's number has also changed over time: it was numbered 252 in 1990, 253 in 1994–1998, 80 in 2002–2009, and 79 in 2013–2021. Since the 2025 election, it has been number 78.

The constituency has had several representatives since its creation. Gero Pfennig of the Christian Democratic Union (CDU) represented it from 1990 to 1998. The Social Democratic Party (SPD) won it in 1998, with Renate Rennebach serving until 2002 and Klaus Uwe Benneter until 2005. Karl-Georg Wellmann of the CDU was elected in 2005 and served until 2017. Since then, Thomas Heilmann of the CDU has represented the constituency.

The constituency's geography and representation history reflect its evolution since reunification, with changes in both boundaries and political leadership.
