The Olympiastadion (Olympic Stadium) is a sports stadium in Berlin. There have been two stadia on the site: the present facility, and one that was built for the aborted 1916 Summer Olympics. Both were designed by members of the same family, the first by Otto March and the second by his son Werner March.

The current Olympiastadion surrounded by the massive Olympischer Platz was originally built for the 1936 Summer Olympics. During World War II, these buildings suffered little damage. After the war, the United Kingdom military occupation used part of the site (not the actual stadium) as its headquarters until 1994.

Aside from its use as an Olympic stadium, the Olympiastadion has a strong footballing tradition. Historically, it is the ground of club Hertha BSC Berlin. It was also used for 3 matches in the 1974 FIFA World Cup. It hosted six matches, including the final, in the 2006 FIFA World Cup and was renovated for that reason. The German Cup final match is held each year at the Olympiastadion in Berlin.
