Tell Sultan (Arabic: تل سلطان; also spelled Tall as-Sultan) is a town in northwestern Syria, administratively part of the Idlib Governorate, located southeast of Idlib and 37 kilometers southwest of Aleppo.

Nearby localities include Abu al-Thuhur to the southeast, Tell Mardikh to the southwest, Saraqib to the west and Tell Touqan to the northwest.

It received this name after Alp Arslan, the sultan of the Seljuk Empire, encamped at the hill during his siege of Aleppo in 1070 CE.

[3] The town was visited in the early 13th century by the geographer Yaqut al-Hamawi who noted it was a "day's march from Halab (Aleppo) towards Damascus" and that it contained "a caravanserai and a rest-house for travelers".

[4] Later, in 1232, the regent queen of Aleppo, Dayfa Khatun received Fatima Khatun, the daughter of Ayyubid sultan al-Kamil, and Baha ad-Din ibn Shaddad at a ceremony in Tell Sultan.
