Amsterdam Oost is a part of the municipality of Amsterdam situated in the East of the Singelgracht. The western boundary is formed by the Amstel river. The southern boundary is the Ringvaart along Watergraafsmeer.

The construction of the eastern town extensions started in the last quarter of the 19th century, with the development of the Oosterparkbuurt and the Dapperbuurt. In the year 1900 also the construction of the Indische buurt (Indian quarter) started.

Between 1920 and 1940 new town extensions were prefaced, partially on the territory of the former municipality Nieuwer Amstel (New Amstel), amongst others the Transvaalbuurt. Since 1987 / 1990 the Transvaalbuurt and Indische buurt (Indian quarter) form the district Oost (East), with the Indian quarter also representing a part of the district Zeeburg.

During the twenties also in the municipality of Watergraafsmeer new town extensions were put into progress. The district Watergraafsmeer was reformed in 1987.

In 1998, the town parts Oost and Watergraafsmeer were merged, forming the new district Oost / Watergraafsmeer. In 1990 new buildings were constructed in the Oostelijk Havengebied (Eastern Docklands) of the district. Since 2002 IJburg has been built, which initially was indicated as Nieuw Oost (New East).
