The Garrwa people, also spelt Karawa and Garawa, are an Aboriginal Australian people living in the Northern Territory, whose traditional lands extended from east of the McArthur River at Borroloola to Doomadgee and the Nicholson River in Queensland.

Together with the Waanyi language, Garrwa belongs to the Garrwan language family, and had two dialects: the heavy eastern Guninderri and the light western variety of Garrwa. Its status within the larger Pama-Nyungan family is disputed: though it shares some features, it also displays many innovative forms that are rare in other Australian languages, suggesting that it fits a distinctive typology.

Tindale calculated the extent of Garrwa lands at approximately 6,300 square miles (16,000 km²). They were in his view an inland people whose northern extension ran only as far as roughly the margins of the coastal plain some 40 miles (64 km) from the Gulf of Carpentaria's coastline. Their territory was rocky, crossing the plateau from the Robinson River homestead and the Foelsche River, running as far south as the headwaters of the former and Seigalls Creek Homestead. Their eastern flank went beyond Calvert Hills as far as east to Wollogorang close to the Queensland border and to the Westmoreland outstation.

Maps have the Yanyuwa people to the north of the Garrwa, the Waanyi and Gudanji to their south, and the Yukulta / Ganggalidda to their east. Today the Garrwa people consider themselves related to the area along the Gulf of Carpentaria coastline of Queensland, around the Wearyan and Robinson Rivers. Two other groups, the Binbinga and Wilangarra became extinct soon after the beginning of white colonisation. The Garrwa habitat extended from the northern tropical, with its mangroves to southern semi-arid inland, with its sandstone gorges. According to the seasons, they would venture into the Bukalara (Barkly Tableland). They see themselves as a freshwater people, distinct from the saltwater peoples to the north and east, harvesting food available in the riverine ecosystem – crayfish, turtles, tubers and waterlies – along with land game such as kangaroo, echidnas and possums.

Drawing on a paraphrase by the historian Tony Roberts, the leading modern authority on the Garrwa Ilana Mushin identifies as part of Garrwa lands the area described in the journal kept by Ludwig Leichhardt as he travelled an old aboriginal trade route through the southern coastal area, as that is. The area concerned, now called the Port McArthur Tidal Wetlands System, lay around the Robinson and Wearyan rivers, and Leichhardt

described emu traps around waterholes, fish traps and fishing weirs across rivers, well-used footpaths, major living areas with substantial dwellings, wells of clear water and a sophisticated method of detoxifying the otherwise extremely poisonous cycad nuts. There were moderately high concentrations of people leading an industrious lifestyle. All of this was markedly different to the stereotyped images of 'savages' leading a 'nomadic' and 'primitive' existence.'

The Garrwa now co-manage the Ganalanga-Mindibirrina Indigenous Protected Area, formed in 2015 through the Waanyi Garawa and Garawa Ranger groups.

The Garrwa were divided into clans, the name of which one at least is known.
