The Island line (Chinese: 港島綫) is one of ten lines of the MTR, the mass transit system in Hong Kong. It runs from Kennedy Town in the Western district to Chai Wan in the Eastern District on Hong Kong Island, passing through the territory's major business districts of Central, Wan Chai and Causeway Bay, and connecting them with built-up areas on the north shore of the island.

The line first opened on 31 May 1985. As of 2022 it travels 16.3 kilometres (10.1 mi)^[2] in 25 minutes along its route, serving 17 stations. The line is indicated in dark blue colour on the MTR route map.

The siding at Tai Koo used to lead all the way out to the seashore, in order to facilitate the moving in of rolling stock, and to connect to a temporary depot used before the one at Chai Wan was opened. Most of the tracks have been removed and the tunnel filled in for the construction of Lei King Wan.
