Cumshewa is a former village of the Haida people located on the north flank of Cumshewa Inlet in the Haida Gwaii of the North Coast of British Columbia, Canada.

It is named for Cumshewa, an important Haida chief during the maritime fur trade.

[1] The name was long in use on marine charts but was made official in the British Columbia gazette on April 6, 1926.

[2] Cumshewa is a Heiltsuk word meaning "rich at the mouth of the river".

The ancient Haida name for the village was Thlinul anglicized as Tlkinool by John Work during a Hudson's Bay Company census in 1839.
