Eemshaven (Dutch pronunciation: [eːmsˈɦaːvə(n)]; English: Ems Harbor) is a seaport in the province of Groningen in the north of the Netherlands.

In 1968, the Dutch government declared the Ems estuary (Eemsmond) to be an economic key region.

One endpoint of the COBRAcable HVDC transmission line to Esbjerg, Denmark is also planned to be built here.

Eemshaven is the landfall point for a high-speed transatlantic fiber-optic cable that connects the U.S. and Europe.

On 23 September 2014, Google announced that it plans to spend $773 million building a data center.
