老松族（老挝文：ລາວສູງ [láːw sǔːŋ])，拉丁转写：Lao Soung）是老挝的三大民族集团之一，占老挝9%的人口，它包括了苗族（其中白苗人口较多）、瑶族、彝族、兰丁族、拉祜族等诸多苗瑶语族、藏缅语族的民族。

他们多居住于老挝北部的山区（上寮），以川圹省、华潘省、琅勃拉邦人数最多。“老松（ລາວສູງ）”一词的意思是“住在高地的老挝人”，其中ສູງ音译为Soung、松，意思是高，和汉语“耸”是同源词。

他们多是在14至18世纪由湖南与云南越过哀牢山南下的。他们多数有种罂粟。他们也曾反巴特寮，重要人物是王宝。

Lao Sung or more commonly Lao Soung (Laotian: ລາວສູງ [láːw sǔːŋ]) is an official Laotian designation for highland dwelling peoples in Laos (the others being the Lao Loum and the Lao Theung). Lao Soung make up 9% of the Laotian population in Laos.

They mostly practice indigenous religions classified together as Satsana Phi, including Lao phi worship, and Yao Taoism. Some practice Theravada Buddhism. Some Lao Soung fought against the communist Pathet Lao government in 1975 to keep the Royal Lao Government in power. Many moved from southern China and Laos to the U.S., France and Australia in the 1960s, 1970s, and 1980s to escape the communist governments there.
