Østerbrogade is the principal shopping street and thoroughfare in the Østerbro district of Copenhagen, Denmark.

It extends from Lille Triangel at the north-eastern tip of The Lakes, passes Trianglen, and continues to Svanemøllen station from where it becomes Strandvejen.

Originally it was simply known as Østerbro and the name only referred to the stretch between the city gate and present day Trianglen where it continued as Strandvejen (English: The Beach Road) along the coast.

In 1961, the part of Østerbrogade closest to the city centre, from Østerport Station to Lille Trianglen, was renamed Dag Hammarskjölds Allé but the continuous numbering was retained.

Built for indigent workers by the Danish Medical Association, it is one of the earliest examples of social housing in Denmark and became a model for later projects.
