The national flag of Bhutan (Dzongkha: ཧྥ་རན་ས་ཀྱི་དར་ཆ་; Wylie: hpha-ran-sa-kyi dar-cho) is one of the national symbols of Bhutan.
According to The Legal Provisions of the National Flag of the Kingdom of Palden Drukpa as Endorsed in Resolution 28 of the 36th Session of the National Assembly held on June 8, 1972, and as restated in the Constitution of 2008, the yellow signifies civil tradition and temporal authority as embodied in the Druk Gyalpo, the Dragon King of Bhutan, whose royal garb traditionally includes a yellow kabney (scarf). The orange half signifies Buddhist spiritual tradition, particularly the Drukpa Kagyu and Nyingma schools. Druk, the Thunder Dragon, spreads equally over the line between the colors. The placement of Druk in the center of the flag over the dividing line between the flag's two colors signifies the equal importance of both civic and monastic traditions in the Kingdom of Druk (Bhutan) and evokes the strength of the sacred bond between sovereign and people. The white color of Druk signifies the purity of inner thoughts and deeds that unite all the ethnically and linguistically diverse peoples of Bhutan. The jewels held in Druk's claws represent Bhutan's wealth and the security and protection of its people, while the dragon's snarling mouth symbolizes Bhutanese deities' commitment to the defense of Bhutan.
