Greetsiel is a small port on the bight of Leybucht in western East Frisia, Germany that was first documented in letters from the year 1388. Since 1972, Greetsiel has been part of the municipality of Krummhrn, which has its administrative seat in Pewsum. The nearest railway station is at Emden, about 1520 kilometres away, and the two towns are linked by a bus service.
The place was founded by the Domain of Appingen under the chiefs of Cirksena. While Appingen increasingly lost its importance, Greetsiel became the seat of the chief. In 1462 Count Edzard the Great was born at the Cirksenaburg under his rule East Frisia extended from the River Weser as far as Groningen. In 1547 Ubbo Emmius was born here. On old Dutch maps the town is marked as Grietjezijl.
