Yidinjdjin

The Yidinjdjin, or Yidiny, are an Aboriginal Australian people of the lowland rainforests around Cairns in Far North Queensland. Their lands ran from Deeral north to the Barron River, inland to Mount Hypipamee and east to the Prior Range. To their north lay the coastal Djabugay, while to the south their borders met the Ngajanji and the Mamu.

They were divided into clans, including the Gimuy, custodians of the Cairns area, and the Walubara. They spoke Yidiny, a Pama-Nyungan tongue of the Yidinic branch closely akin to Djabugay.
