Zătreni is a commune situated in the Oltenia region of Romania, specifically within Vâlcea County. It serves as an administrative division composed of fourteen distinct villages: Butanu, Ciortești, Dealu Glămeia, Dealu Văleni, Făurești, Mănicea, Mecea, Oltețu, Sășcioara, Stanomiru, Valea Văleni, Văleni, Zătreni, and Zătrenii de Sus.
The geographical boundaries of the commune were modified in 2004. During this time, five villages—Contea, Gănești, Lăcusteni, Lăcustenii de Jos, and Lăcustenii de Sus—were separated from Zătreni to establish the independent Lăcusteni Commune.
