Ma On Shan Road (Chinese: 馬鞍山路) is a major expressway in the new town of Ma On Shan in the New Territories of Hong Kong. The expressway extends northward from Tate's Cairn Highway near Tai Shui Hang along the eastern bank of Shing Mun River. It ends in the north when it joins Sai Sha Road near Wu Kai Sha. Its branch road, Ma On Shan Bypass, redirects traffic between Sha Tin and Sai Kung away from the town centre near Heng On Estate. It is the primary thoroughfare to Ma On Shan, which is locally nicknamed as Center of the universe (in Cantonese).
