The Yellabinna Regional Reserve is a Regional Reserve in South Australia, 30 km north of Ceduna. To the west it borders Nullarbor Regional Reserve, to the south Yumbarra Conservation Park and Pureba Conservation Park. In the northwestern Section the 5,030 km² Yellabinna Wilderness Protection Area (YWPA) is almost entirely surrounded by the Regional Reserve. The northern border in the western half of the Reserve is formed by the Trans-Australian Railway.
The arid landscape is characterized by red sand dunes. The wildlife is adapted to the dry climate. Typical species are scarlet-chested parrots, major mitchell's cockatoos, thorny devils, sandhill dunnarts and malleefowls. The reserve is outside of the dingo fence, which borders it in the east. Therefore it is situated in the area, where dingoes are tolerated.
