Dhaka is a town and Nagar Parishad (municipal council) located in East Champaran district of Bihar, India. It serves as the administrative headquarters of the Sikrahana subdivision and has developed into a significant administrative, commercial, and educational centre in the northern part of East Champaran district.
The town functions as a regional hub within East Champaran's transport and trade network. It is connected to the district's broader transportation system through Mehsi, a historically important transport and trade centre that serves as the Gateway of Champaran. Together, Dhaka and Mehsi form two key regional centres that support commerce, transportation, and public services across different areas of East Champaran, with Mehsi linking the southern portions of the district to northern border towns including Dhaka itself.
