The Tintina Trench is a large valley extending through Yukon, Canada. It is the northern extension of the Northern Rocky Mountain Trench in British Columbia and it has its origin from the Tintina Fault.
The northern part of the valley is occupied by the Pelly River, a tributary of the Yukon River.
The southern Tintina Trench is drained by the Liard River which first flows south-eastward, then eastward and finally merges into the Mackenzie River at Fort Simpson, NWT where the combined waters turn back north for the Mackenzie's long flow to the Arctic Ocean.
Communities and features of the Trench include the following:
