The spelling "Kyuquot" adapted in 1863 by Captain Richards, RN, referring to the local tribe. Elsewhere, Mr. George Clutesi, Sechart Band of the Nootka [Indigenous People] [sic] advised that Kyuquot means "other or foreign" people (advice to Provincial Archives.)

The correct form of the traditional name is Koh:too, a reference to fishing boundaries. (December 2010 advice from Ka:'yu:'k't'h'/Che:k:tles7et'h' First Nations.)

Names after the Nuu-chah-nulth First nations inhabitants of Kyuquot Sound, who originally consisted of four separate tribes, each with its own winter village, and gathered each summer of Aktis Island (formerly known as Village Island). Kyuquot has been translated as “different people” or “foreign people” and appears to be a name applied by Nuu-chah-nulth groups to the south. The name has written many different ways in the old days, including Caiyuquat and Cayuquet; today the preferred spelling is Ka:’yu:K’t’h. The Ka:’yu:K’t’h people amalgamated in the 1950s and ‘60s with the Checleset (Che:K’tles7et’h’), who originally occupied territory farther northwest, and moved with them in the 1970s to Houpsitas, located on Vancouver Island just northeast on Aktis Island, close to the fishing village and commercial centre of Walters Island (qv). The modern community of Kyuquot is quite spread out and generally refers to Houpsitas, Walters Island and several other small, inhabited islands.
