Dordrecht (Dutch pronunciation: [ˈdɔrdrɛxt]), 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 118,782 in 2014. 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 the Holland area and has a rich history and culture.

The name Dordrecht comes from Thuredriht (ca 1120), Thuredrecht (ca 1200). The name seems to mean 'thoroughfare'; a ship-canal or -river through which ships were pulled by rope from one river to another, as here from the Dubbel to the Merwede, or vice versa. Earlier etymologists had assumed that the 'drecht' suffix came from Latin 'trajectum', a ford, but this was rejected in 1996. The Drecht is now supposed to have been derived from 'draeg', which means to pull, tow or drag. 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.

The city was formed along the Thure river, in the midst of peat swamps. This river was a branch of the river Dubbel, which is part of the massive Rhine–Meuse–Scheldt delta complex, near the current Bagijnhof. Around 1120 reference to Dordrecht was made by a remark that count Dirk IV of Holland was murdered in 1049 near "Thuredrech".
