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.

Bukhara is the seventh-largest city in Uzbekistan by population, with 280,187 residents as of 1 January 2020. It is the capital of Bukhara Region. The mother tongue of the majority of people of Bukhara is the Tajik dialect of the Persian language, although Uzbek is spoken as a second language by most residents.
