Lazaretto Island, (Greek: Λαζαρέτο, also Lazareto, formerly known as Aghios Dimitrios) is located two nautical miles northeast of the city of Corfu.

The island has an area of 7 ha (17 acres) and is administered by the Greek National Tourist Organization.

In 1798, during the French occupation, it was occupied by the Russo-Turkish fleet which ran it as a military hospital.
