Wat Khao Chedi is a small hillside Buddhist temple located on the island of Koh Samui, in Thailand. Set on a quiet elevation overlooking parts of the coastline and surrounding jungle, it is known for its peaceful atmosphere and relatively uncrowded setting compared to more famous temples on the island.

The temple features a simple but striking chedi (stupa) structure, along with traditional Thai architectural elements such as prayer halls, Buddha statues, and decorative details. Its hilltop position provides occasional views across the landscape, with glimpses of the sea and nearby hills visible through the trees. The surroundings are calm and shaded, with tropical vegetation adding to the sense of seclusion.

Today, Wat Khao Chedi is primarily visited by those seeking a quieter spiritual experience or a break from the busier tourist areas of Koh Samui. It remains an active place of worship, where local monks and visitors alike come for meditation and reflection, making it a modest but meaningful cultural site on the island.
