Route 8 (Chinese: 八號幹線) of Hong Kong is a dual 3-lane carriageway motorway that links Lantau Island, Tsing Yi Island, Cheung Sha Wan in West Kowloon, and Sha Tin in the southeast New Territories of Hong Kong.

The section between Tsing Yi and Cheung Sha Wan, formerly known as Route 9, is a 7.6 km (4.7 mi) dual 3-lane expressway.

This section provides traffic with a more direct route to the Lantau Link, particularly vehicles from Tsim Sha Tsui and Western Harbour Crossing, previously vehicles had to use Route 3 (Cheung Tsing Bridge and Cheung Tsing Tunnel).

The remaining section links Cheung Sha Wan and Tai Wai, formerly known as Route 16.

The remaining section of the Tsing Sha Highway was opened to traffic on 20 December, and the same day also marked the full completion of Route 8.
