مجمعالجزایر مالایی نام گروه بزرگی از جزیرهها در جنوب شرقی آسیا، بین هندوچین و استرالیا است.
این مجمعالجزایر بزرگترین گروه از جزیرهها در جهان است و بیش از ۱۳ هزار جزیره از اندونزی و در حدود ۷ هزار جزیره از فیلیپین را شامل میشود.
در محل، این منطقه را بیشتر با نام «هند شرقی» مینامند.
گاه گینه نو را نیز بخشی از این مجمعالجزایر بهشمار میآورند.
The 19th-century naturalist Alfred Wallace used the term "Malay Archipelago" as the title of his influential book documenting his studies in the region. Wallace also referred to the area as the "Indian Archipelago" and the "Indo-Australian" Archipelago. He included within the region the Solomon Islands and the Malay Peninsula due to physiographic similarities. As Wallace noted, there are arguments for excluding Papua New Guinea for cultural and geographical reasons: Papua New Guinea is culturally quite different from the other countries in the region, and it is geologically not part of the continent of Asia, as the islands of the Sunda Shelf are (see Australia).
The climate throughout the archipelago is tropical, owing to its position on the equator.
Wallace's line between Australian and Southeast Asian fauna. The deep water of the Lombok Strait between the islands of Bali and Lombok formed a water barrier even when lower sea levels linked the now-separated islands and landmasses on either side.
Wallace used the term Malay Archipelago as the title of his influential book documenting his studies in the region. He proposed what would come to be known as the "Wallace Line", a boundary that separated the flora and fauna of Asia and Australia. The ice age boundary was formed by the deep water straits between Borneo and Sulawesi; and through the Lombok Strait between Bali and Lombok. This is now considered the western border of the Wallacea transition zone between the zoogeographical regions of Asia and Australia. The zone has a mixture of species of Asian and Australian origin, and its own endemic species.
"If we draw a line ... commencing along the western coast of Gilolo, through the island of Bouru, and curving round the west end of Mores, then bending back by Sandalwood Island to take in Rotti, we shall divide the Archipelago into two portions, the races of which have strongly marked distinctive peculiarities. This line will separate the Malayan and all the Asiatic races, from the Papuans and all that inhabit the Pacific; and though along the line of junction intermigration and commixture have taken place, yet the division is on the whole almost as well defined and strongly contrasted, as is the corresponding zoological division of the Archipelago, into an Indo-Malayan and Austro-Malayan region."
