Nieuwmarkt (Dutch pronunciation: [ˈniuˌmɑr(ə)kt]; English: New Market) is a square in the centre of Amsterdam, Netherlands.

The square is considered part of Amsterdam's Chinatown, next to the De Wallen (Red Light District).

The Nieuwmarkt is dominated by a building known as the Waag,[1] originally a gate in the Medieval city walls but converted into a weighing house after the walls were demolished in the 17th century.

In World War II the square was used by the Nazis as a collection point for Jews who had been rounded up to be sent to the concentration camps.

[1] In the 1970s many buildings on and around the square were torn down to make way for a planned metro and four-lane highway,[2] which was to run right through the Nieuwmarkt neighbourhood.
