In Salah or Ain Salah (Arabic:عين صالح‎) is an oasis town in central Algeria. It was once an important trade link of the trans-Saharan caravan route. As of the 2008 census it has a population of 32,518, up from 28,022 in 1998, with an annual growth rate of 1.5%, the lowest in the province. The village is located in the heart of the Sahara Desert region of northern Africa. The name In Salah comes from the term "good well" although the water is known for its rather unpleasant, salty taste.
