Khao Chang (เขาช้าง), is a 45 m high hill in Phang Nga Province, Thailand.

Located within the compound of Wat Phra Paht Phra Chim temple, at the base of a mountain, is Phung Chang Cave, also known as 'Elephant Belly Cave.'

Certain areas of the cave are permanently flooded, but they remain accessible to visitors via boat.

[1] In the cultural context of Phang Nga, Khao Chang holds significant symbolic value.

Its towering shape resembles a crouched elephant, a feature that has led to its inclusion in the provincial seal of Phang Nga.
