Aughinish is a former island (now peninsula) in the Shannon estuary, in County Limerick, Ireland, near Foynes.

Rusal Aughinish, Europe's largest bauxite refinery, is located on the island.

[1] The site includes a deep-water jetty in the Shannon[2] through which the refinery imports bauxite from Guinea and Brazil and exports alumina to be refined into aluminium metal.

[1] Although most of the island is occupied by industry, it is also the site of Ireland's first butterfly sanctuary, located in an abandoned quarry.
