The Ehattesaht are a Nuu-chah-nulth First Nation on the west coast of Vancouver Island. They formerly consisted of three bands who, decimated by disease and warfare, amalgamated in the historic period. In 2008 there were about 300 registered Ehattesaht. Their traditional territories include the north shore of Esperanza Inlet and the outer coast, Zeballos Inlet and part of Espinosa Inlet. The main Ehattesaht villages were Oke and Tatchu, but today the main village is Chenahkint at Queen's Cove. The Ehattesaht traditionally were major suppliers of dentalia shells, highly valued as trade objects by Aboriginal peoples of the Northwest Coast.

Ehattesaht are one of the 14 nations represented by the Nuu-chah-nulth Tribal Council.
