The La Ha (Vietnamese: người La Ha) are an ethnic group of Vietnam. Most La Ha live in the Yên Bái and Sơn La provinces, and numbered approximately 5,686 people in 1999. They speak the Laha language, which is part of the Tai–Kadai language family.
The La Ha celebrate the Pang A Nụn Ban Festival to show deep gratitude to their doctors. They offer them bitter bamboo and Mạ Rệ flower, both of which are popular drugs.
