Brinkin is a northern suburb of Darwin, the capital city of the Northern Territory, Australia. It is located 12 kilometres (7 mi) north of Darwin's central business district, and is home to the Casuarina campus of Charles Darwin University (formerly Northern Territory University's campus). It is the traditional country and waterways of the Larrakia people.

Brinkin is named after an Aboriginal people who inhabited an area to the south of the Daly River mouth, the Marrithiyal people, sometimes referred to by other tribes in the past as Brinken. The streets in Brinkin are named after boats which serviced the coast of northern Australia.

The suburb was constructed in 1984, and the university followed several years later.

Brinkin is located on Darwin Harbour coastline at the southern end of Casuarina Beach, and is bounded by Trower Road to the north, Ellengowen Drive to the east and part of Rapid Creek and a stormwater drain to the south. The suburb consists of a few residential blocks to the north of the university, the university itself, a coastal reserve and part of the Rapid Creek Wetlands.

Ellengowan Drive in Brinkin was named after the SS Ellengowan, the oldest known shipwreck in Darwin harbour
