Udalguri district is one of the 27 districts of Assam state in north-eastern India. Udalguri town is the headquarters of the district.
The name of the district is derived from its headquarters, Udalguri. There are three traditions regarding the etymology of Udalguri. According to one tradition, the name is derived from Odal (a tree) and Guri (roots or surrounding) and it was named because originally the town developed around an Odal tree. According to another tradition, this town derived its name because this place was originally a hermitage of sage Uddalaka. According to the third tradition, the name is derived from two Bodo words Ordla (wide and spacious) and Gundri (powdered object).
