Lab-i Hauz, sometimes also known as Lyab-i Khauz, a Russian approximation, is the name of the area surrounding one of the few remaining hauz pools that have survived in the city of Bukhara, Uzbekistan. Until the Soviet period, there were many such pools, which were the city's principal source of water, but they were notorious for spreading disease and were mostly filled in during the 1920s and 1930s.
