布鲁夏斯基语（乌尔都语：بروشسکی‎，ISO 233：B(u)rwš(a)skỳ），即勃律语，是一种中亚的语言，语言人口约有8.7万（2000年统计）。此种语言的用户都是勃律人（Burúšo），勃律人当中有5万到6万人口居住在克什米尔北部的坎巨提、那格尔等地山区。由于山区地方偏僻，各地的居民都形成了各自的方言体系。现时的布鲁夏斯基语的词汇里除了固有的字词以外，还有相当数量从乌尔都语及其他周边民族而来的借词。这些借词，有些来自达尔德语支（Dardic languages）。布鲁夏斯基语有三种方言，取名于当地的三个主要山谷。这三种方言分别为：洪扎Hunza、那格尔Nagar及亚辛Yasin。
