The British explorer and navigator George Vancouver camped on Ketron Island in May of 1792.
The island's name in the Lushootseed language is saʔilc, meaning "bad rock". The island was originally named "Kittson Island" in English by Charles Wilkes during the Wilkes Expedition of 1838–1842, but was misspelled "Ketron" by his cartographers. The island was named for William Kittson, an employee of the Hudson's Bay Company, who supervised the construction of Fort Nisqually in 1833 and served as its chief factor.
The entire island was bought by an entrepreneur in 1946 with plans to build 200 homes, but this attempt was abandoned due to the cost of a sewer system.
