Lhuentse Dzong is a dzong and Buddhist monastery in Lhuntse District in eastern Bhutan. It lies on the eastern side of the Kuri Chhu and is perched on a spur at the end of a narrow valley. The Dzong was initially known as Kurtoe in the then-isolated Lhuntse District. It is the ancestral home of the House of Wangchuck. While its geographic coordinates are in eastern Bhutan, its cultural roots are central Bhutanese. This was because before road traffic connected it to Mongar, the approach was through a trade route crossing Rodang Pass.
