D'Aguilar Peak, Mountain summit in Southern District, Hong Kong.

D'Aguilar Peak, also called Hok Tsui Shan, is a 325-metre hill in southeastern Hong Kong Island. Its northern summit area lies within Shek O Country Park, and Shek O Peak stands to the north. The summit is reached by a road linking to Cape D'Aguilar Road on the southwestern side of the peninsula.

The peak was named after Major-General Sir George Charles d'Aguilar during Britain's colonial period in Hong Kong. This naming reflects the European influence that shaped the geographical terminology of the region.

The Cantonese name Hok Tsui Shan refers to the crane's beak shape of the peninsula, while the English name honours Major-General Sir George Charles d'Aguilar. Hikers on the Dragon's Back trail see the peak but the trail does not cross its summit.

The walk to the summit takes about 30 minutes from Cape D'Aguilar Road, or you can start from Shek O Beach for an alternative route. Different starting points work for different fitness levels and preferences.

The Site of Special Scientific Interest covers 5 hectares on the northwestern slope, south of Windy Gap, and was designated in 1975. The summit itself lies outside the Shek O Country Park boundary, which takes in the area north of the top. The hill is named after Major-General Sir George Charles d'Aguilar.
