Eighter Island (Irish: An tÍochtar) is a small island and a townland[2] off the coast of County Donegal, Ireland.

The island is located around one km east of Arranmore and North-West of Inishcoo, another small island divided by narrow channels from Rutland and the mainland.

A footbridge connects the two islets, both known for pleasant sandbeaches.

Some of the old houses are used as holiday homes, mostly concentrated in the south-eastern part of the island.
