The North Island line is a shelved proposal to provide rapid transit service for the area between the existing MTR Island line and the northern coast of Hong Kong Island in order to relieve the congested Island line.

Originally, according to the document "Rail Projects Under Planning 2000" released by the Highways Department,^[1] the current Tung Chung line would be extended from Hong Kong terminus eastward and two new stations, Tamar station and Exhibition Centre station are proposed on the extension. The new route would then connect and continue on the Island line from Fortress Hill station to Chai Wan terminus. The Tseung Kwan O line will have newly constructed tunnels connected from its North Point terminus to Fortress Hill station and continue on the remaining western half of the Island line.

In 2013, the Highways Department released a second option for the North Island line scheme, also known as the "interchange scheme" because it will only extend the Tung Chung line and the Tseung Kwan O line to meet at Tamar station where it will act as an interchange station for the two lines without dividing the Island line. The original scheme is known as the "swap scheme" for distinction.
