Named by Robert Brown, commander of the Vancouver Island Exploring Expedition, 1864: "....This lake I named Henderson lake, after my friend Captain John Henderson, who first communicated to me the supposed existence of this body of water, which may probably yet be of considerable value for inland communication, as the little outlet could be easily suited for the entrance of vessels at a comparatively small expense." (Report to the Royal Geographic Society of the Vancouver Island Ex Ex...p.23).

"Captain John Henderson, master mariner...who came out to this coast in command of the fine composite barquentine "Woodpecker", which vessel brought out the machinery for the Alberni Saw Mill Company in 1860. The Woodpecker, the property of the company, a short time after discharging her cargo at Alberni, was totally lost at the entrance of the Columbia river; crew saved. Captain Henderson, in 1862, commanded the Saw Mill Company's schooner Alberni... the 3rd vessel built on this coast since the building of the North West America in Friendly Cove in 1877 (Victoria Colonist, 5 July 1862). The Alberni, some years afterwards, was taken to the Sandwich Islands, sold and converted into a whaler. In 1863 Henderson had charge of the company's steamer Thames, and in this vessel in 1865 was engaged in salvage operations at Trail isalnd on the stranded sailing vessel Elizabeth Kimball (Victoria Colonist 25 January 1865). He subsequently returned to England, and died in command of the ship Red Riding Hood."

The Uchucklesaht name for Henderson Lake is Houtchucklis (Uchucklesaht Tribe Communications Coordinator, October 2008); "Uchucklesaht Tribe membership traditionally used this lake as well as the lands and mountains around the lake for their spiritual practices. This lake has always been very precious and spiritual to the people of Houtchucklis." (September 2010 advice from Uchucklesaht Tribe). Spelling updated to Hucuktlis Lake per 1 March 2011 advice from Uchucklesaht Tribe.
