The Watergraafsmeer (Dutch pronunciation: [ˌʋaːtərɣraːfsˈmeːr]) is a polder in North Holland, Netherlands.
It is among the lowest-lying parts of Amsterdam (approximately 5 metres below the NAP).
Since 1921, the Watergraafsmeer is part of the city of Amsterdam and its rural character has all but disappeared.
During the 17th and 18th centuries, a number of wealthy Amsterdammers (inhabitants of Amsterdam) built buitenplaatsen in the Watergraafsmeer.
From 1 May 1817 until 1 January 1921, Watergraafsmeer was an independent municipality with approximately ten thousand inhabitants.
