Heerstraße, or Heerstrasse (see ß;[2] German pronunciation: [ˈheːɐ̯ˌʃtʁaːsə] ⓘ; literally: Army Street), runs from Theodor-Heuss-Platz in Berlin-Charlottenburg to the western city border of Berlin in the locality of Staaken in the borough of Spandau.

With a length of around 10 kilometres, it is one of the longest streets in Berlin and an important commuter route.

The street is a five-lane expressway (Kraftfahrstraße), depending on traffic flow the middle lane is available during rush hours in the morning (eastbound) and in the evening (westbound).

In 1911 the street was opened in full length as Döberitzer Heerstraße in attendance of Emperor Wilhelm II.

Heerstraße starts at Theodor-Heuss-Platz in Westend of Charlottenburg district, close to the exhibition ground, the Funkturm and the International Congress Centre (ICC).

From there the Heerstraße runs south of the Olympic Stadium and passes a former housing area (nicknamed "Little Britain") of the British Forces in Berlin.

Pichelsdorfer Straße runs from Heerstraße northbound and connects from here to the Spandauer Altstadt (Oldtown).

The next crossing is Sandstraße, which was until it was cut in the early 1970s, was leading to another housing area of the British Forces.

The continuing of Heerstraße as Bundesstraße 5 in the Federal State of Brandenburg is named Hamburger Chaussee.

It leads through the Havelland, crosses the Berlin Ring and runs via Hamburg right up to the Danish border.
