Heriz rugs are Persian rugs from the area of Heris, East Azerbaijan in northwest Iran, northeast of Tabriz. Such rugs are produced in the village of the same name in the slopes of Mount Sabalan. Heriz carpets are extremely durable and hard-wearing and they can last for generations. 19th century examples of such carpets are often found on sale by major auction houses in United States and Europe. New Herizes are thick, tough, and often reasonable in price. Such rugs age well and become more and more beautiful with age. Part of the reason for the toughness of Heriz carpets is that Mount Sabalan sits on a major deposit of copper. Traces of copper in the drinking water of sheep produces high quality wool that is far more resilient than wool from other areas.^{[citation needed]}

Heriz rug weavers often make them in geometric, bold patterns with a large medallion dominating the field. Such designs are traditional and often woven from memory.

Similar rugs from the neighbouring towns and villages of Ahar, Heris, Mehraban, Sarab, Bakhshaish, and Gorevan are often marketed as Heriz but compare poorly with original Herizes.^{[citation needed]}

Heriz rugs are of coarse construction. The rugs range from 30 kpsi on the low end to 100–10 kpsi on the high end. It is rare to see a rug over 100 kpsi that would look like an authentic Heriz unless it is an antique silk Heriz.
