|Umpila Sign Language|
The land territory associated with the Umpila language group is located along the northeastern coast of Cape York Peninsula and stretches from the northern end of Temple Bay south to the Massey Creek region at the top of Princess Charlotte Bay, and west of the Great Dividing Range towards the township of Coen. Most of the remaining Umpila and Kuuku Ya'u speakers reside in Lockhart River Aboriginal Community, which is located at Lloyd Bay, roughly at the boundary between Umpila and Kuuku Ya'u lands.
The chief varieties of Umpila, variously considered dialects or distinct languages, are:
- Umpila proper
