Adopted 2 February 1926 on C.326 (file H.1.26 pt.1). Name first appears on British Admiralty Chart 1923B, published 12 December 1867 from surveys undertaken by Capt. Daniel Pender and officers of HMS Beaver in 1866; the island is unnamed on an 1865 chart of the same area, suggesting that the name came into use in 1866 or 1867. Origin & significance of name not known; although there has been speculation of a connection between "Swindle" Island and "Price" Island nearby to the south, it is known that Capt. Pender had named Price Island after Captain John Adolphus Price, RN.
