بحر ناتونا

بحر ناتونا (إندونيسية: Laut Natuna؛ إنگليزية: Natuna Sea) هو بحر ضحل شاسع حول جزر ناتونا ويمتد جنوباً حتى ليڠگا و أرخبيل تامبلان في محافظة جزر رياو، إلى الجنوب من جزر باڠكا بليتوڠ، إندونيسيا. ومعظم هذا البحر يقع ضمن المياه الإقليمية الإندونيسية، وجيولوجياً هو جزء من رصيف سوندا. ويحد هذا البحر بحر الصين الجنوبي شماله وشماله الشرقي، و مضيق كاريماتا إلى الجنوب الشرقي، و مضيق سنغافورة إلى الغرب.

Previously, this part of sea was considered as a part of South China Sea. However, in 1986 the International Hydrographic Organization (IHO) officially recognizes the Natuna Sea, which extends south from the Natuna and Anambas Islands to the Belitung Islands.
