The law of Bhutan derives mainly from legislation and treaties. Prior to the enactment of the Constitution, laws were enacted by fiat of the King of Bhutan. The law of Bhutan originates in the semi-theocratic Tsa Yig legal code, and was heavily influenced through the twentieth century by English common law. As Bhutan democratizes, its government has examined many countries' legal systems and modeled its reforms after their laws.

The supreme law of Bhutan is the Constitution of 2008. Under the Constitution, laws are passed through a bicameral process requiring the assent of the National Assembly and National Council of Parliament, as well as the assent of the King. The final authority on law of Bhutan and its interpretation is the Supreme Court. Laws enacted in Bhutan prior to the Constitution of 2008 remain intact insofar as they do not conflict with the Constitution.

Much of Bhutanese law is premised on promoting Gross National Happiness, a fundamental principle of the Constitution.

The law of Bhutan is enforced by the national police, established in 1965. The judicial system of Bhutan, namely the Royal Court of Justice, brings and hears cases and interprets the law of Bhutan. Agencies of Ministries within the Lhengye Zhungtshog (Cabinet) as well as independent Commissions are established by law to implement relevant laws, provide regulations, and establish procedural frameworks.

Bhutan (Dzongkha: འབྲུག་ཡུལ་, tr ʼbrug-yul, "Druk Yul"; Devanagari भूटान, Bhūṭān), officially the Kingdom of Bhutan, is a landlocked state in South Asia, located at the eastern end of the Himalayas and bordered to the south, east and west by the Republic of India and to the north by the People's Republic of China. Bhutan is separated from the nearby country of Nepal to the west by the Indian state of Sikkim, and from Bangladesh to the south by the Indian states of Assam and West Bengal.

Bhutan existed as a patchwork of minor warring fiefdoms until the early 17th century, when the area was unified by Shabdrung Ngawang Namgyal, who fled religious persecution in Tibet and cultivated a separate Bhutanese identity. In the early 20th century, Bhutan came into contact with the British Empire, after which Bhutan continued strong bilateral relations with India upon its independence. In 2006, Business Week rated Bhutan the happiest country in Asia and the eighth-happiest in the world, based on a global survey.
