The Federgo, also Federitga, was a historic region, situated on the northwestern edge of East Frisia, by the Wadden Sea, which roughly covered the present-day parish of Krummhörn.[1] Before the breach of the Leybucht bay the parish of Norden also belonged to Federgo.[2] The gau probably derives its name from the conspicuous marsh plants growing there.
The Federgo is bordered in the east by the Brokmerland and in the south by the Emsigerland.
