Borgohain (Ahom language: Chao Thao Lung) was the second of the two original counsellors in the Ahom kingdom. He was selected by the Ahom king from members of the Ahom nobility (Satgharia Ahom), who was not eligible for the position of Ahom kingship. The other original counsellor is the Burhagohain. Both the positions existed from the time of the first Ahom king, Sukaphaa. The Borgohain administered the region south of the Dikhow river to Koliabor.
