Der Abi Saeed (Arabic: دير أبي سعيد) is a city in Irbid Governorate in Jordan. It is named after a historic Christian chapel ('Der' in Arabic) in the place where the city is built. The city gained importance in the early 20th century after the formation of a self-governing body following the fall of the Ottoman Empire. Der Abi Saeed is the administrative center of the Koura Department, one of the nine departments of Irbid Governorate.
The city is located in the Jordanian part of the Houran Plateau, about to the southwest of the city of Irbid in the province of Irbid Governorate, and about to the north from Jordan's capital Amman.
In 1838 Der Abi Saeed's inhabitants were predominantly Sunni Muslims.[2]
The Jordanian census of 1961 found 1,927 inhabitants in Deir Abu Sa'id.[3]
