Eira[1] is a river in Molde Municipality in Møre og Romsdal county, Norway. The 7km (04miles) long river flows from the lake Eikesdalsvatnet past the village of Eresfjord and into the Eresfjorden. The mountain Skjorta lies east of the river.
Historically, the river was a bountiful salmon fishing area, but since it has become a regulated river for nearby hydro-electric power stations, the fish have not been as plentiful.
