Uchquduq (sometimes spelled as Uchkuduk, Uzbek: Üçquduq; Russian: Учкуду́к) is a city in the north of Navoiy Region, Uzbekistan.

In the late 1960s, the development of open pit and underground mining led to the rapid growth of the settlement, with workers, engineers and technicians from all over the Soviet Union.

Until 1979, Uchquduq had the status of a "closed secret city," as it supplied much of the raw material for nuclear weapons in the Soviet military arsenal.
