Ban Yang is a village in Luang Prabang district, Luang Prabang province, Laos. It was established around 1935 by Lao Loum ethnic group who used to live in Ban Pha Quang village in Phu Phang Mountain. Ban Pha Quang village is 20 kilometers northeast from Mueang Nan district, Luang Prabang province. When they arrived, they saw this region had immense forested mountain, fertile land, abundant water source in the Huoi Sieu stream, and was convenient for living and farming. They also discovered a big tree with its roots crossing the Huoi Sieu stream like a bridge. The tree root that later was named as Yang, means 'crossing the stream'. Since then, people have called this village Ban Yang.
