The Emden-Pewsum-Greetsiel light railway (German: Kreisbahn Emden-Pewsum-Greetsiel) was originally a private railway operated by the district of Emden in East Frisia in North Germany.

It ran through the Krummhörn landscape via Hinte and Pewsum to the port of Greetsiel on the bay of Leybucht.

(From the official name of Emden station the railway postal stamp used on the light railway was "Emden−Larrelt−Greetsiel", which appeared to refer to the non-existent station of Larrelt, but was just a short way of writing "Emden-Larrelter Straße − Greetsiel".)

Passenger and goods services began on 27 July 1899 from Emden to Pewsum and were extended as far as Greetsiel from 21 September 1906.

From 1933, operations were run by the Hanover State Light Railway Office, later the Lower Saxon State Railway Office at Hanover (NLEA).
