Tate's Cairn Highway (Chinese: 大老山公路; pinyin: Dàlǎoshān Gōnglù; Cantonese Yale: daai5 lou5 saan1 gung1 lou6), opened on 26 June 1991, is a dual 3-lane expressway in Hong Kong. It links Tate's Cairn Tunnel and Ma Liu Shui Interchange, forming a part of Route 2 (formerly known as Route 6).

From the Ma Liu Shui Interchange, where it connects with Route 9, the expressway crosses the estuary of the Shing Mun River. It then turns southwards, interchanging at Shek Mun with a distributor road (Tai Chung Kiu Road), and reaches Siu Lek Yuen, where the highway splits. One branch leads to Tate's Cairn Tunnel (which continues as Route 2), and the other leads to Sha Lek Highway, which eventually joins Route 1 at Sha Tin Road.

The highway is named after Tate's Cairn.

Tate's Cairn Highway in its entirety falls within the boundaries of Sha Tin District.
