The island of Lunga is the largest of the Treshnish Isles in Argyll and Bute, Scotland.

The Isles are part of the Loch Na Keal National Scenic Area.

[8] These designations reflect the importance of the island for its marine life, including the grey seals that inhabit the waters around it, and for its breeding colonies of seabirds, including storm-petrels, kittiwakes, Manx shearwaters, guillemot, puffin, European shag and razorbills.

(The birds also breed on the Harp Rock, a sea stack separated from Lunga by a narrow gut.)

[3] In summer, tourist boats visit Lunga from Ulva Ferry, Tiree, Tobermory, Iona and Ardnamurchan.
