Jomsom (), also known as Dzongsam (New Fort) is the centre of Gharapjhong rural municipality in Mustang district and a former independent village development committee situated at an altitude of about in Gandaki Pradesh of western Nepal. The soaring peaks of Dhaulagiri and Nilgiri form a backdrop to the town straddling the Kali Gandaki River, which flows right through the centre of Jomsom. Along the banks of the Kali Gandaki, black fossilized stones called shaligram, considered as an iconic symbol and reminder of the god Vishnu in the Hindu culture, can be found. Such stones are believed to be found only in the Kali Gandaki, and are holy to the Hindus.
