The Duar War (or Anglo-Bhutanese War) was a war fought between British India and Bhutan in 1864 to 1865. It was the only military conflict between the two states since 1774 and resulted in Bhutan losing a fifth of its territory.

As a result of the war, Bhutan lost its independent foreign policy capabilities for several decades.
