Berlin-Marzahn-Hellersdorf was created after German reunification in 1990. Until 2002, it was named Berlin-Hellersdorf-Marzahn. In the 1990 election, it was constituency 261 in the numbering system. In the 1994 and 1998 elections, it was number 260. In the 2002 through 2009 elections, it was number 86. In the 2013 through 2021 elections, it was number 85. From the 2025 election, it has been number 84. Its borders have not changed since its creation.

Berlin-Marzahn – Hellersdorf was considered a safe seat for The Left and its predecessor Party of Democratic Socialism (PDS), which won the constituency in every election since 1990 and even in the 2002 German federal election, where it was only one of two seats the then-PDS won nationwide. However, Petra Pau, who first won the seat in 2002 following the retirement of incumbent member Gregor Gysi, lost re-election in the 2021 German federal election. She lost by nearly eight percentage points to Mario Czaja (CDU), who had previously won a Abgeordnetenhaus of Berlin constituency entirely within the borough (Marzahn-Hellersdorf 5) multiple times by large margins.
