哈里斯毛料是由哈里斯岛及路易斯岛为首的几个苏格兰岛屿居民利用当地盛产的羊毛手工织成的衣料。 传统的哈里斯毛料特色是带有杂色的斑点。这些斑点是借由数种植物染剂，包括几种采自苔癣，称为"crottle"的染料染成的。染剂分别带有紫咖啡、铁锈橘的颜色，这些颜色成就了哈里斯毛料的著名特色。

Harris Tweed is a cloth handwoven by islanders at their homes in the Outer Hebrides of Scotland, finished in the Outer Hebrides, and made from pure virgin wool dyed and spun in the Outer Hebrides.

Harris Tweed is protected by the Harris Tweed Act 1993, which strictly outlines the conditions in which the cloth can genuinely be made.
