West Kowloon Highway () is a section of Route 3 in Hong Kong, built as part of the Airport Core Programme. This dual-three-lane expressway runs for 4.2 km, connecting Western Harbour Crossing in the south with Tsing Kwai Highway in the north. While the southern section of the road is at grade, the northern part is on a viaduct in order to accommodate the MTR Tung Chung line and the Airport Express.
