The Djabugay people (also known as Djabuganydji or Tjapukai) are a group of Aboriginal Australian people who are the original inhabitants of mountains, gorges, lands and waters of a richly forested part of the Great Dividing Range including the Barron Gorge and surrounding areas within the Wet Tropics of Queensland.

Djabugay belongs to the Yidinic branch of the Pama–Nyungan language family, and is closely related to Yidin. It shares the distinction, with Bandjalang in north-eastern New South Wales and South East Queensland, and Maung spoken on the Goulburn Islands off the coast of Arnhem Land, of being one of only three languages that lack the dual form. The last speaker with a good knowledge of the language was Gilpin Banning.

Norman Tindale described the territory of the Tjapukai (Djabugay) as extending along the plateau south of and to the east of south of Mareeba, from Barron River, south of Mareeba to Kuranda and north toward Port Douglas. Their western boundary was defined by the margin of the rain forest from Tolga north to Mount Molloy. By 1952, the Djabugay claimed also the coastal strip between Cairns Inlet and Lamb Range, with one horde lived near Redlynch, Cairns.

The Djabugay word for their ancestral times, beyond their living memory, (also known as 'Story time' or 'Dreamtime') is bulurru. This was a time when, for instance, it is told the Rainbow Serpent Gudju Gudju, in the form of a giant carpet snake (aka Budadji) traveled through the country, bartering with families along the way for rainforest products such as dilly bags) in exchange for coastal nautilus shells, his body creating within the landscape everything from Yaln giri (Crystal Cascades) to Ngunbay (Kuranda), moving through the Mowbray River to the hill at Port Douglas, finally coming to rest at Wangal Djungay (Double Island). In one account, he was killed by emu men at 'Din din (the Barron Falls), an incident which unleashed the powerful monsoonal rains on the region. There were also 2 Bulurru dreamtime brothers, Damarri and Guyala, who laid down the contours, created the plant foods, and established the customary law and the system of clan marriage by moieties. The contours of the Barron River and Redlynch Valley, for example, are thought of as representing the supine body of Damarri.

The tale of Budadji's travels along the Barron Gorge is included in the web guide of Queensland Rail to the railways journey from Cairns to Kuranda.

European settlers explored and cleared the land for gold and tin. "Dispersals," the euphemism for massacring groups of native Australians, were undertaken at Smithfield (1878), at Biboohra near the Clohesy River close to Kuranda in the early 1880s, and also near Mareeba in 1881.

In May 1886, a railway was constructed from Cairns to Herberton with part of the rails going on top of a walking track. The Djabugay were unhappy about this development and withstood the settlement by spearing bullocks and settlers. As the settlers entered, traditional hunting and gathering grounds were taken over.

This led to the notorious Speewah massacre in 1890 where John Atherton took revenge on the Djabugay by sending in native troopers to avenge the killing of a bullock. The Djabugay were segregated from them and forced to live at the Mona Mona Aboriginal Mission and were unable to hunt, fish, or move around. Their numbers fell dramatically at the turn of the century.
