Chaatl, also spelled Cha'atl, Tsaa'ahl, Tts’aa’ahl, and other variations,[2][3] was a historic Haida village located on the shore of Chaatl Island, facing south across Buck Channel to the western side of northern Moresby Island,[4] near the western end of Skidegate Channel, Haida Gwaii, British Columbia, Canada.

[10][5][1] Chaatl was founded by families of the Raven and Eagle moieties from a long-abandoned village known as "Pebble Town", at Second Beach near Skidegate.

When the HBC took over they focused the coast trade on Fort Simpson (today called Lax Kwʼalaams) on the mainland, not far from Prince Rupert.

[10] In the 1860s, during the Haida village abandonment and consolidation era that followed multiple epidemics, especially the 1862 Pacific Northwest smallpox epidemic, survivors in Chaatl moved to the eastern end of Skidegate Inlet, mostly to a new town on Maude Island (Haida: Xaayna Gwaay[11]) established by refugees from Kaisun.

In the 1890s, after suffering further epidemics of smallpox, measles, and other diseases, the survivors in Haina moved to the new mission town of Skidegate, which had displaced the old Haida village of Hlghagilda.
