Tambora is the poorly attested non-Austronesian (Papuan) language of the Tambora culture of central Sumbawa, in what is now Indonesia, which was wiped out by the 1815 eruption of Mount Tambora. This was the westernmost known Papuan language (Donohue 2007), and was relatively unusual among such languages in being the language of a maritime trading state, though contemporary Papuan trading states were also found off Halmahera in Ternate and Tidore.
