Huney is an uninhabited island due east of the island of Unst in the Shetland Islands, Scotland. The island is located approximately 1 kilometre south west of Balta and has an area of just under 0.2 km2. Huney is separated from Unst by a narrow channel called The Yei. At extremely low tides a sandy tombolo may connect Huney to Unst. The World War I British E-class submarine HMS E49 was sunk in the channel between Huney and Balta with the loss of 3 officers and 28 ratings on 12 March 1917. The submarine was heading out of Balta Sound on patrol when it struck a naval mine probably lain by German U-boat SMU UC-76. The wreck is now a designated war grave.
