Al'Usaylah is a place in Wadi Al'Usaylah, northeast of Makkah. It is in a valley on the old Hajj caravan route from the north. This valley is fertile and was once called the valley of Khalid ibn Asid.

At this site, there are more than sixty inscriptions carved into the rocks on the Mountains of al-Wajrah. These writings are from the 1st and 2nd Hijri centuries (7th and 8th centuries CE).

There were originally four wells here, but now only two wells remain.
