The Marrithiyal are an indigenous Australian people whose traditional territory lay 30 to 50 miles south of the Daly River in the Northern Territory. They were sometimes known derogatively as Berringen(Berinken/Brinken), a term used by the Mulluk-Mulluk to refer to 'aliens'/strangers'.
Marrithiyal is classified as one of the Daly River Languages Areal group, one of the prefixing non-Pama–Nyungan languages, exhibiting a distinctive phonemic inventory rare among Australian tongues. The Marrithiyal recognize three dialect variants: Marri Ammu, Marridan, and Marrisjabin, and at last count (2006) had an estimated 6 surviving speakers, though slightly earlier the figure had been put at 30. Most now speak a variety of Kriol. The autonym Marrithiyal has been conjectured to be derived from a combination of the words mari (speech) and thiel, meaning paperbark, suggesting the idea that the ethnonym denotes a 'people of the paperbark tea tree swamps', reflecting the fact that their homeland was rich in paper-bark forests. It was considered, by both whites and natives in the area, as particularly euphonious, especially compared to the 'rougher' sounding language of the Wagiman further west up river.
In the Marrithiyal version of the Dreamtime story of the rainbow serpent, the serpent, lacking a wife, stole one from a flying fox who had two. The latter retaliated by spearing the rainbow serpent who plunged into the water, while the flying fox soared up to the sky. It is one variation on a story which has many different versions in this area.
Their traditional grounds lay south-west of the Majar hill in Madngella territory (now known as Hermit Hill) between the Daly and Fitzmaurice Rivers. Like a dozen other tribes, as the white invasion got underway in the 1880s, the remnants either dispersed or crammed into a small strip of alluvial flats, a territory about 20 miles long, extending from the middle to the lower reaches of the Daly, mostly displacing the original tribes of that area which had almost become extinct by the 1930s. Many Marrithiyal, as the tribe broke up, spread out into a variety of locations, some shifting to the lands of the former Kungarakany Tyaraity, and Wogait peoples, others taking up jobs in Darwin, at the Daly River peanut farms or working as stockmen at the Mt. Litchfield cattle station, or drifting into the Port Keats mission station.
