Ti-Tree (formerly Tea Tree and Ti Tree) is a town and locality in the Northern Territory of Australia located on the Stuart Highway about 1,109 kilometres (689 mi) south of the territory capital of Darwin[1][4] and about 193 km north[citation needed] of the municipal seat in Alice Springs.

The area is an emerging centre for grapes and melons due to its year-round sunshine and abundant underground water supply.

Since the construction of the Overland Telegraph Line, Tea Tree Well had become known for its good supply of sweet water but this was not enough to make Heffernan's labours financially rewarding.

Much of the area surrounding Ti Tree township is now within the bounds of the Ahakeye Land Trust, an Aboriginal Freehold Lease.

In 1980, the local community petitioned the Northern Territory Legislative Assembly to change the spelling from "Tea Tree" to "Ti-Tree".

Ti-Tree is the centre for a vegetable-producing area, producing fresh vegetables and fruit for Territory markets, with an annual table-grape harvest alone reaping $10 million.

In 2018, the school offered Reception to Year 9, had a total enrolment of 80 students of which 96% were indigenous and had a teaching staff of six who was supported by seven non-teaching personnel.
