Sultanabad rugs are floor coverings of distinctive design made in Arak, Iran (formerly known as Sultanabad) since the 19th century.

Most similar to the Sultanabads are Heriz and Serapi rugs; this similarity is attributed to the designs' magnificent graphic character. Yet within this similarity, Heriz/Serapis designs tend to be more curvilinear and classical. Sultanabads share with Persian rugs all-over designs of palmettes and vine scrolls, but as they use a larger, suppler weave, the Sultanabad designs tend to be larger.
