Lark Harbour is small fishing community on the western coast of Newfoundland, on the south side of the Bay of Islands, and west of the City of Corner Brook.

Combined with neighbouring York Harbour, there is a population of about 1,100. Blow-Me-Down Provincial Park lies on the boundary between the two communities.

Captain James Cook and the naming of Lark Harbour and York Harbour

Local legend has it that James Cook named the harbours after two of his ships. However, while it is true that Cook spent the years 1764 to 1767 surveying and charting the coasts of Newfoundland and was working in the Bay of Islands in the summer of 1767, he had charge of only one ship, the schooner Grenville. Not a naval vessel, and built and operated in Massachusetts under the name Sally, she had been purchased by the Royal Navy for Cook's use while surveying.

HMS Lark and HMS York, after which the harbours were named, were ships of the Royal Navy's Newfoundland Squadron. To command such ships a naval commission was required, and Cook held no such commission during his years in Newfoundland: he was at that time a sailing master. The title of captain, or commander, was reserved for commissioned officers of the Navy.
