The Sharda River (Hindi: शारदा नदी, shāradā nadī) or Mahakali River (Nepali: महाकाली नदी, mahākālī nadī) is also called Kali Gad (Hindi: काली गाड, kālī gād) or Kali Ganga in Uttarakhand where the river demarcates Nepal's western border with India. This boundary was established by the 1816 Sugauli treaty. The name is sometimes written "Sarda".

The river descends from 3,600 metres (11,800 ft) at Kalapani to 200 metres (660 ft) as it enters the Terai plains, offering an unrealized potential for hydroelectric power generation. The river is also proposed as source for one of the many projects in the Himalayan component of the Indian Rivers Inter-link project.

Below the Nepal-Uttarakhand border the river enters Uttar Pradesh state and flows southeast across the plains to join the Ghaghra river, a tributary of the Ganges.

The traditional source of the (Maha)Kali is the pond of the Kali temple at Kalapani. The geographic sources, however, are some five kilometers further north and some thousand metres higher: streams emerging from glaciers along the watershed with the uppermost Humla Karnali. India's border with China's Tibet Autonomous Region follows this watershed. Below Kalapani the river has been Nepal's western border with India since the Sugauli Treaty concluding the Anglo-Nepalese War of 1814–16.
