Dettah is a special community in the Northwest Territories, Canada. It is a First Nations community, meaning it is home to one of Canada's original peoples. You can find Dettah in the North Slave Region, just southeast of Yellowknife, the capital city.

The name T'é?ehdaá means 'Burnt Point' in the Wíílíídeh language. This was the original name used by the local people. Later, it was simplified to Dettah because it was easier for non-Indigenous people to say. For a long time, this spot was a popular place for the Tetsǫ́tʼine (Yellowknives) people to fish. Today, about 200 Indigenous people live here.

You can get to Dettah from Yellowknife in two ways. In winter, when the Great Slave Lake freezes, you can drive across the ice road. This short drive is about 6.5 kilometers (4 miles). The rest of the year, you take a longer drive of about 27 kilometers (17 miles) on the Ingraham Trail.
