Lanka is a town located in Hojai District of Assam, and a municipal board with 11 wards.

It serves as a trade and commerce hub for nearby areas such as Udali, Nokhuti, Laskar Pather, Karikhana, Kheroni, Dablong, and Doiyong sides.

An inscription of the 13th century discovered near Dabaka has the following lines about Lanka: “ Kachhar rajyad jayantay lankanta rajyabanta Yajnamenong daabeka mandali mathastha karyamasa.” The Lankeswari Temple is of historical significance for the place.

This fact is recorded in the documents concerning the numerous journeys undertaken by Guru Nanak in various stages of his life.

It is said that he had Srimanta Shankardeva, the founder of the Mahapuruxiya Dharma as the Guru travelled from Dhaka to Assam.

While some died and some came back to Punjab, a few stayed on and made Assam their home, raising families.

Their descendants today —mainly concentrated in the Nagaon district — are Assamese for all practical purposes, and none speaks Punjabi, but continue to maintain their Sikh identity and observe most tenets and traditions of the religion.

Bengalis form the majority of the town's population, having Bengali speakers at 30,051 constituting the largest majority, while Assamese speakers are 2,918 as the second-largest minority in the circle, Hindi is spoken by 2,408 people, while other languages constitute 3.9% of the population.
