Sardinia is the second largest island in the Mediterranean Sea (after Sicily and Cyprus) and an autonomous region of Italy. It is located in the Western Mediterranean, south of Corsica.

To the west of Sardinia is the Sea of Sardinia, a unit of the Mediterranean Sea; to Sardinia’s east is the Tyrrhenian Sea, which is also an element of the Mediterranean Sea.

The coasts of Sardinia (1,849 kilometres (1,149 miles) long) are generally high and rocky, with long, relatively straight stretches of coastline.
