The Jiri plain is an area of gravel plain extending across areas of Southern Ras Al Khaimah, Eastern Sharjah and Western Fujairah, United Arab Emirates (UAE).

[1] The area, some 15 miles in length and 8 miles in breadth, is triangulated with the villages of Khatt and Habhab to the North; Adhen to the East and Dhaid to the South.

[2] The soil of the Jiri plain is darkened by debris brought down by seasonal waters from the mountains, which helps to define its rich, loamy character and high carbonate content (from the outwash of Cretaceous limestone).

[2] The settled population of the area at the time of Lorimer's 1908 Gazetteer of the Persian Gulf was some 1,000 strong, mostly members of the tribes of Awanat, Mazari, Naqbiyin, Sharqiyin (in the area of Wadi Ham)[4] and some Zaab.

[5] The plain, together with that of Dhaid and Madam, contains some of the most fertile and productive land in the UAE.
