Doueir ( Arabic: دوير, al-Dwayr), or Dweir, is a village of 7,500 inhabitants in Southern Lebanon near Nabatieh, and north of the Litani River. It is located directly next to the village of charquieh. Although Doueir is considered a small village, it is the home of many well-known Lebanese such as former Labour minister Ali Qanso, Mehdi Kanso, and the late nuclear physics scientist Rammal Rammal.
During the 2006 Lebanon War, Doueir was among the first targets of the Israel Defense Forces, with a family of 12 killed on July 13. The village has since benefited from investment by the Italian government to build a new olive oil mill.
