The Three Sharp Peaks of Hong Kong () are a collection of three peaks that Hong Kong hikers deem as very challenging to summit because of loose rocks and steep inclination. The peaks are Castle Peak (583m) in Tuen Mun, Sharp Peak (468m) in Sai Kung and High Junk Peak (344m) in Clear Water Bay. The three peaks are scattered in different regions in Hong Kong. While Castle Peak is the tallest of the three, Sharp Peak is generally considered the hardest of the three because of its remoteness and steepness.
