Adam Graham Giles is an Australian former politician and former Chief Minister of the Northern Territory (2013–2016) as well as the former leader of the Country Liberal Party (CLP) in the unicameral Northern Territory Parliament. Giles is the first Indigenous Australian to serve as a head of government in Australia.

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.
