刚毛猪笼草（学名：）是婆罗洲特有的热带食虫植物。其最大的特点就是披被着厚厚一层棕色的毛被，而其他猪笼草多只在花序上具毛被。捕虫笼多为全绿色，内表面具一些红色的斑点。其种加词“hirsuta”来源于拉丁文“hirsūtus”，意为“多毛的，刚毛的”。

刚毛猪笼草生长于海拔200米至1100米处。其分布广泛于荒原森林、覆满苔藓的低地山地森林、开阔地和山脊下部的灌木丛。其通常生长在砂质土壤上。

刚毛猪笼草与粗毛猪笼草和大型平庸猪笼草之间存在着密切的近缘关系。植物学家马修·杰布和马丁·奇克还认为刚毛猪笼草与菲律宾巴拉望特有的菲律宾猪笼草之间存在着密切的近缘关系。

在食虫植物数据库中，分类学家简·斯洛尔将粗毛猪笼草列为刚毛猪笼草的同物异名。
