Hellersdorf (German pronunciation: [ˈhɛlɐsˌdɔʁf] ⓘ) is a locality in the borough of Marzahn-Hellersdorf in Berlin.

Between 1986 and Berlin's 2001 administrative reform, it was a borough in its own right, consisting of the current area of Hellersdorf as well as Kaulsdorf and Mahlsdorf.

Situated at the eastern part of Berlin, the area is mainly a large housing estate from the 1980s, made up of Plattenbau (concrete slab) buildings.

The historic village of Helwichstorpp was first mentioned in a 1375 land registry of Emperor Charles IV, then also Margrave of Brandenburg.

During German reunification on October 3, 1990, a small part of Hönow (primarily around the last two stations of U5) was annexed by this borough.
