Denis Gabriel Burke is a former Australian politician. A former Australian Army officer, he served as a Country Liberal Party member of the Northern Territory Legislative Assembly from 1994 to 2005. He spent two years as Chief Minister after succeeding Shane Stone, but oversaw the CLP's defeat at the 2001 election, ending 27 years of continuous CLP government in the Northern Territory. Burke later served as Opposition Leader from 2001 to 2003 before being toppled, but was re-elected as leader in 2005. He subsequently took the party to its largest-ever defeat at the 2005 election, culminating in the shock loss of his own seat.

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.
