Kareng (Pron:/ˌkɑ:ɹɛŋ ˈgɑ:/, "royal palace"), also known as The Garhgaon Palace, is located in Garhgaon 15 kilometres (9.3 mi) from Sivasagar, Assam, India.

In 1751 Sunenphaa, son of Sukhrungphaa, constructed the brick wall of about 5 kilometres (3.1 mi) in length surrounding the Garhgaon Palace and the masonry gate leading to it.

After the destruction of the old palace it was rebuilt around 1752 as the present seven-storied structure by Suremphaa (1751–1769).

The earliest constructions were commissioned by Sukhrungphaa in 1698 AD.
