Miles Island is a rocky island 3nmi long, lying just north of Booth Peninsula in the Mariner Islands, Antarctica. It was mapped from air photos taken by U.S. Navy Operation Highjump in 1946–1947, and was named by the Advisory Committee on Antarctic Names for R.A. Miles, an air crewman on Operation Highjump photographic flights in this area and other coastal areas between 14° and 164° East longitude.
