Auskerry (Scots: Soond; Old Norse: Austrsker, east skerry) is a small island in eastern Orkney, Scotland.

Auskerry is a small, flat, red sandstone islet, 3 miles (5 km) south of Stronsay.

The Hastings County, a 116-metre Norwegian cargo ship, ran ashore on north west of Auskerry in 1926 during thick fog.

Auskerry is designated a Special Protection Area due to its importance as a nesting area for Arctic tern and European storm petrel; 4.2% of the breeding population of European storm petrels in Great Britain nest on the island.

[17] The island has been designated an Important Bird Area (IBA) by BirdLife International because it supports significant breeding populations of seabirds.
