The chief minister of the Northern Territory is the head of government of the Northern Territory. The office is the equivalent of a state premier. When the Northern Territory Legislative Assembly was created in 1974, the head of government was officially known as majority leader. This title was used in the first parliament (1974–1977) and the first eighteen months of the second. When self-government was granted the Northern Territory in 1978, the title of the head of government became chief minister.

The chief minister is formally appointed by the administrator, who in normal circumstances will appoint the head of whichever party holds the majority of seats in the unicameral Legislative Assembly. In times of constitutional crisis, the administrator can appoint someone else as chief minister, though this has never occurred.

Since 21 December 2023, following the resignation of Natasha Fyles, the chief minister is Eva Lawler of the Labor Party. She is the third female chief minister of the Northern Territory.

The Country Liberal Party won the first Northern Territory election on 19 October 1974 and elected Goff Letts majority leader. He headed an Executive that carried out most of the functions of a ministry at the state level. At the 1977 election Letts lost his seat and party leadership. He was succeeded on 13 August 1977 by Paul Everingham (CLP) as Majority Leader. When the Territory attained self-government on 1 July 1978, Everingham became chief minister with greatly expanded powers.

In 2001, Clare Martin became the first Labor and female chief minister of the Northern Territory. Until 2004 the conduct of elections and drawing of electoral boundaries was performed by the Northern Territory Electoral Office, a unit of the Department of the chief minister. In March 2004 the independent Northern Territory Electoral Commission was established.

In 2013, Mills was replaced as chief minister and CLP leader by Adam Giles at the 2013 CLP leadership ballot on 13 March to become the first indigenous Australian to lead a state or territory government in Australia.^[2]
