Ningombam is a surname which is used by a large number of Meitei. It is a clan belonging to the Angom dynasty, one of the seven kingdoms in the present state of Manipur. It is considered to be the oldest clan in Manipur and the kings of Angom had tremendous powers over the other kings in the ancient history of Manipur. Ningombam being a royal scion had the traditions of marrying the princesses of the royal families namely Rajkumaris of Manipur.
The term "Ningombam" got transformed from "Ningomba" due to the introduction of "m" as a suffix in every surname in the era of Hinduism being spread in Manipur, a few hundreds years ago. From "Cheitharol Kumbaba" - the Meitei puya or the oldest sacred book, it is discovered that Khui Ningomba ruled the then kingdom of Manipur from 363-378 A.D.
