Dordrecht (Dutch pronunciation: [ˈdɔr.trɛχt] ( listen)), colloquially Dordt [dɔrt], historically in English named Dort, is a city and municipality in the western Netherlands, located in the province of South Holland. It is the fourth largest city of the province, having a population of 118,601 in 2009. The municipality covers the entire Dordrecht Island, also often called Het Eiland van Dordt (the Island of Dordt), bordered by the rivers Oude Maas, Beneden Merwede, Nieuwe Merwede, Hollands Diep, and Dordtsche Kil. Dordrecht is the largest and most important city in the Drechtsteden and is also part of the Randstad, the main conurbation in the Netherlands. Dordrecht is the oldest city in Holland and has a rich history and culture.

The name Dordrecht comes from Thyre, the name of a river, and Middle Dutch drecht "ford", thus meaning "Thure river crossing". Some documentation speaks of the river actually being called Thuredrith. Inhabitants of Dordrecht are Dordtenaren (singular: Dordtenaar). Dordrecht is informally called Dordt by its inhabitants. In earlier centuries, Dordrecht was a major trade port, well-known to British merchants, and was called Dort in English.
