A modification of the Haida name for Port Louis, with ‘kathli’ meaning ‘open bay.’ Some early maps show this name Kyokathli or Kai Qa-ti. In his British Columbia Place Names, Capt John Walbran claims that Kiokathli Inlet was formerly named Port Ingraham, after early US fur trader Joseph Ingraham, but Ingraham’s own journal, published 1971, indicates that Port Ingraham was the feature now known as Nesto Inlet.
