Kinakuta (also Queena-Kootah) is a fictional island nation that is more prominently featured in Cryptonomicon.
Many of the members of the Cabal travel to Kinakuta, although the travel is not depicted in the Baroque Cycle. The tiny nation is dominated by a mountain, which Jack Shaftoe names Mount Eliza in honor of his lady love.
In Cryptonomicon (page 191), Avi pinpoints Kinakuta as lying in the strait between Borneo and Palawan. This would place it close to (or as a replacement and enlargement of) the real-world Banggi Island .
