Muaither (Arabic: معيذر) is a district of Al Rayyan City in Qatar, located in the municipality of Al Rayyan.
Referencing the area’s geography, ‘muaither’ is derived from the Arabic ‘mathar’, meaning “place where animals are kept”. Muaither is situated in a rawda (depression), meaning that water runoff accumulates in it, leading to increased plant activity. Various perennials such as the samr tree and fennel grow here. As such, the area serves as a good grazing area for Bedouins rearing their livestock.
