Lombok is an
island in
West Nusa Tenggara province,
Indonesia. It forms part of the chain of the
Lesser Sunda Islands, with the
Lombok Strait separating it from
Bali to the west and the
Alas Strait between it and
Sumbawa to the east. It is roughly circular, with a "tail" (
Sekotong Peninsula) to the southwest, about 70 km across and a total area of about 4,514 km² (1,825 sq mi). The provincial capital and largest city on the island is
Mataram. It is somewhat similar in size and density with neighboring
Bali and shares some cultural heritage, but is administratively part of Nusa Tenggara Barat along with sparsely populated
Sumbawa. It is surrounded by a number of smaller islands locally called
Gili.
