Purmerend (Dutch pronunciation: [ˌpʏrməˈrɛnt] ) is a city and municipality in the west of the Netherlands, in the province of North Holland. The city is surrounded by polders, such as the Purmer, Beemster and the Wormer. Purmerend's population grew relatively slowly until the 1960s, when it increased from around 10,000 to over 80,000 by 2020. This expansion has turned Purmerend into a commuter town; many inhabitants (14,200 in 2011) work, go to school or spend leisure time in Amsterdam. Purmerend is part of the Randstad, one of the largest conurbations in Europe.
The municipality of Beemster merged into the municipality of Purmerend on 1 January 2022. The extended municipality has a population of about 96,000.
