Smugglers' Ridge or Ma Tsz Keng (Chinese: 孖指徑) is a hill with a height of 337 metres (1,106 ft) in New Territories, Hong Kong.

A part of Shing Mun Tunnels is built underneath this hill.

By continuing northwest at distance post W066 on the Wilson Trail, instead of the intended route, along a path with sparse woodland, Smuggler's Ridge can be reached.

[3] Smuggler's Ridge rises slowly from its start to the south until steeply dropping at its highest point to the north, where it meets MacLehose Trail stage 6 again at Shing Mun Redoubt.

Tai Mo Shan, Needle Hill and other Kowloon Hills can be seen from Smuggler's Ridge, along with Kwai Chung to the west, parts of Shatin to the east, and Cheung Sha Wan to the south.
