傣阮，又称昆勐，汉语译名又有“泰庸人”、“润族”、“傣允”等，是泰国北部的台语民族，傣泰民族的一个支系，自称＂傣＂，是泰国北部的主要人口，人口600万；也分布于缅甸与老挝，人数逾3万。他们与西双版纳的傣族傣泐有关，曾经创建兰纳王国。 居住在泰国北部兰纳八府的傣阮和傣泐、傣痕、傣龙（掸族）一起，被称作兰纳泰族。

傣阮一称来自于傣族古国庸纳迦，阮即是庸纳迦的简化。

傣阮与居住于泐国的傣族人傣泐有很密切的关系，泰国北部的傣族傣阮祖先来自西双版纳，至今也起码有一半以上的西双版纳傣族的血统。

傣阮使用的文本来自于古孟文，经过改造后传入掸邦景栋、西双版纳和澜沧王国境内。

The Northern Thai people or Tai Yuan (ไทยวน, [taj˧ ɲuːən˧]), self-designation khon mu(e)ang (ฅนเมือง,  [xon˧ mɯːəŋ˧], meaning "people of the (cultivated) land" or "people of our community") are the majority population of eight provinces in northern Thailand, principally in the area of the former kingdom of Lanna. They belong to the group of Tai peoples and are closely related to Tai Lü and Tai Khün with regards to common culture, language and history. There are approximately 6 million Tai Yuan. Most of them live in Northern Thailand, with a small minority 29,442 (2005 census) living across the border in Bokeo and Sainyabuli Provinces of Laos. Their language is called Northern Thai, Lanna, or Kham Mueang.
