The Walmadjari (Walmajarri) people, also known as Tjiwaling and Wanaseka, are an Aboriginal Australian people of the Kimberley region of Western Australia.

The two names reflect different Walmadjari preferences. Their western bands accept Tjiwaling as an ethnonym for as it is a designation peoples neighbouring them further west employ. The eastern bands prefer the Walmadjari autonym, or conversely, define themselves as the Wanaseka, as opposed to the Tjiwaling, side.)^[1]

Walmadjari belongs to the Ngumpin–Yapa branch of the Pama-Nyungan language family.

Norman Tindale's estimation^{[lower-alpha 1]} assigned the Walmadjari roughly 15,000 square miles (39,000 km²) of territory on the desert plateau south of the Fitzroy and Christmas Creek valleys and from Kunkadea(Noonkanbah), as far east as the Cummins Range. Their southern limits ran along the Canning Stock Route to Kardalapuru (Well 47). Sometime in the latter half of the 19th century, a group of Walmadjari, who are called Ngainan, took over some Gooniyandi territory, the downs north of Christmas Creek between Mellon Spring and Landrigan Cliffs.^[1]
