The Kwun Tong line (Chinese: 觀塘綫) is a rapid transit line of the MTR network in Hong Kong, coloured green on the MTR map. Starting at Whampoa in Hung Hom and ending at Tiu Keng Leng in Tseung Kwan O, Sai Kung, the route has 17 stations and takes 35 minutes to complete.^[3] The Kwun Tong line is one of the busiest railway lines on the network connecting the central and the eastern portions of Kowloon via Wong Tai Sin. The line is mostly underground, but includes a lengthy elevated section, and runs generally in an east-west direction. During the morning rush hour, the Kwun Tong line utilises 33 trains running at 29tph (trains per hour) to achieve a route capacity of 85,000 pphpd (passengers per hour per direction).^[3]

Opened on 1 October 1979 as the first urban railway line in Hong Kong and the first operated by the Mass Transit Railway Corporation (MTRC), the Kwun Tong line operates over much of the original section of the "Modified Initial System", from Shek Kip Mei to Kwun Tong station, which it is named after. The line has seen the most changes in alignment of all the MTR lines, the most recent in 2016. It has crossed Victoria Harbour to serve Hong Kong Island using two separate routes in its history, though other lines have since taken over the harbour crossings; as such, the current route lies entirely within Kowloon except for Tiu Keng Leng in the New Territories. It has interchanges with four other lines: the Tsuen Wan line at Yau Ma Tei- Prince Edward station, the East Rail line at Kowloon Tong station, the Tuen Ma line at Ho Man Tin and Diamond Hill station, and the Tseung Kwan O line at Yau Tong and Tiu Keng Leng station.
