Sultan Han is a large and significant 13th-century Seljuk caravanserai located in the town of Sultanhanı, Aksaray Province, Turkey. It is one of the three monumental caravanserais in the neighbourhood of Aksaray and is located about 40 km (25 mi) west of Aksaray on the road to Konya.

Seljuk architecture comprises the building traditions that developed under the Seljuk dynasty, when it ruled most of the Middle East and Anatolia during the 11th to 13th centuries. The Great Seljuk Empire contributed significantly to the architecture of Iran and surrounding regions, introducing innovations such as the symmetrical four-iwan layout and the first widespread creation of state-sponsored madrasas. Their buildings were generally constructed in brick, with decoration created using brickwork, tiles, and carved stucco.
