Delfshaven is a borough of Rotterdam on the right bank of river Nieuwe Maas, in South Holland, the Netherlands. It was a separate municipality until 1886.
The town of Delfshaven grew around the port of the city of Delft. Delft itself was not located on a major river, so in 1389 a harbour was created about 10 km due south of the city, to be able to receive seafaring vessels and avoid tolls being levied by the neighbouring and competing city of Rotterdam. This settlement was named Delfshaven.
On 1 August 1620 the Pilgrim fathers left Delfshaven with the Speedwell. Since then, the town's Oude Kerk has also been known as the Pelgrimskerk, or in English, the "Pilgrim Fathers Church".
