Eemsdelta (Dutch pronunciation: [ˈeːmzˌdɛltaː]) is a municipality in the province of Groningen, Netherlands formed from the merger of Appingedam, Delfzijl and Loppersum.

[4] Delfzijl, Appingedam and Loppersum formally announced their interest in a merger on 16 November 2017 and approved the final plans on 2 January 2018.

[5] Eemsmond was excluded from the plans as it decided to merge with Bedum, De Marne and Winsum instead to form the municipality of Het Hogeland.

[6] In 2019, the planned dissolution of WO DEAL was announced as the municipalities of Het Hogeland and Eemsdelta were deemed to be large enough to be able to handle all their tasks without the need for further cooperation.

[8] The name refers to the river Eems, and has also previously been used as a loosely defined region in the Northeast of Groningen, roughly encompassing the same territory as the municipality[6] and historically known as Fivelingo or Fivelgo.
