Paro District is a district (dzongkhag), valley, river and town in Bhutan. It is one of the most historic valleys in Bhutan. Both trade goods and invading Tibetans came over the pass at the head of the valley, giving Paro the closest cultural connection with Tibet of any Bhutanese district. The dominant language in Paro is Dzongkha, the national language.

Dzongkha is a Sino-Tibetan language that is the official and national language of Bhutan. It is written using the Tibetan script.
