perang bhutan (atau perang bhutan) adalah perang yang terjadi antara india britania dan bhutan pada tahun 1864-1865.
inggris mengirimkan misi perdamaian ke bhutan di awal tahun 1864, di bawah komando ashley eden, dan juga kegiatan ini menjadi awal dari perang saudara di sana.pra= "eden, ashley".
dzongpon (sebuah bangunan mirip benteng) yang ada di punakha  yang memenangkan kemerdekaan  telah rusak oleh pemerintah pusat dan mengatur saingan druk desi ketika druk desi mencari perlindungan dari ponlop dari paro yang kemudian terguling.
misi inggris ditangani secara bergantian oleh sepasang rival ponlop paro dan ponlop dari trongsa (bertindak atas nama druk desi), tetapi sayangnya bhutan menolak perdamaian dan perjanjian persahabatan yang ditawarkan.
oleh karena itu, inggris menyatakan perang pada bulan november 1864.
bhutan pada saat itu belum memiliki tentara yang memadai, dan hanya mengandalkan pertahanan dari benteng dzong dan senjata yang bernama matchlocks, busur serta anak panah, pedang, pisau, dan ketapel.
beberapa penjaga dzong, membawa perisai dan memakai chainmail armor, yang merupakan peralatan pasukan inggris.
benteng, yang dikenal pada saat itu sebagai dewangiri, di deothang dibongkar oleh inggris pada tahun 1865.
inggris awalnya mengalami kekalahan yang memalukan di deothang dan ketika mereka merebut kembali dewangiri mereka menghancurkan banyak dalam upaya untuk mengkompensasi.
perang duar (1864-1865) hanya berlangsung sekitar lima bulan, meskipun beberapa medan perang dimenangi oleh pasukan bhutan, tetapi perang yang tidak sebanding tetap membuat pihak bhutan kalah, dan mengakibatkan mereka kehilangan daerah kedaulatannya, dan memaksa penyerahan dari wilayah-wilayah pendudukan sebelumnya oleh pihak inggris.
di bawah syarat-syarat perjanjian sinchula, yang ditandatangani tanggal 11 november 1865, bhutan menyerahkan wilayah di assam duars dan bengal duars, serta 83 km2 dari wilayah dewangiri di tenggara bhutan, dan kembali dengan kebijakan pajak tahunan 50.000 rupee.
perjanjian sinchula berdiri sampai tahun 1910, ketika bhutan dan india inggris menandatangani perjanjian punakha, efektif sampai tahun 1947.
