Tibetan Empire had nine high ministers in court. The highest one was gung lön chen po (, lön chen () for short), which could be translated into English as "Chief Minister" or "Prime minister".
The first Lönchen was appointed during Detrul Namshungtsen's reign. It was abolished before the Era of Fragmentation.
Here is a complete list of Lönchen according to The Old Tibetan Chronicle (P.T. 1287).
