The Letts Executive was the executive of Majority Leader of the Northern Territory Goff Letts, who led the Northern Territory from the implementation of the Northern Territory Legislative Assembly in 1974 until his defeat in his own seat at the 1977 election. It was the first ministry to come from the Legislative Assembly. He was the only head of government of the Northern Territory not to assume the title of Chief Minister of the Northern Territory, as self-government was not granted until 1978. His governments did not have anywhere near the range of powers available to Territory governments after the granting of self-government, but nevertheless fulfilled similar functions. Letts' successor as Majority Leader and his one-time deputy, Paul Everingham, became the first Chief Minister in 1978.[1][2]
Jim Robertson, MLA, while not technically a member of the executive, served as Manager of Government Business throughout this period.
