Linosa (Italian pronunciation: [liˈnoːza];[1] Sicilian: Linusa [lɪˈnuːsa]; Arabic: نموشة, Nammūša) is one of the Pelagie Islands in the Sicily Channel of the Mediterranean Sea.

The island is cited first as Greek Aethusa (Αἰθοῦσσα) by ancient geographers Strabo and Ptolemy, and as Algusa (Ἀλγοῦσσα) by Roman essayist Pliny the Elder in his Naturalis Historia.

During the Napoleonic Wars, the British considered the possibility of taking over Linosa (together with Pantelleria and Lampedusa) so as to be able to supply Malta, but a Royal Commission stated in an 1812 report that there would be considerable difficulties in this venture.

The first thirty colonists (artisans from Ustica, Agrigento and Pantelleria) with the addition of a mayor, a priest and a doctor, landed on 25 April 1845.

During World War II, a small Italian garrison surrendered[3] to a British force from HMS Nubian on the morning of 13 June 1943.
