Pripyat, also known as Prypiat, is an abandoned industrial city in Kyiv Oblast, Ukraine, located near the border with Belarus. Named after the nearby river, Pripyat, it was founded on 4 February 1970 as the ninth atomgrad ('atom city', a type of closed city in the Soviet Union that served the purpose of housing nuclear workers near a plant), catering the nearby Chernobyl Nuclear Power Plant. The plant is located north of the abandoned city of Chernobyl, after which it is named. Pripyat was officially proclaimed a city in 1979 and had ballooned to a population of 49,360 by the time it was evacuated on the afternoon of 27 April 1986, one day after the Chernobyl disaster.

Although it is located in Vyshhorod Raion, the abandoned municipality is administered directly from the capital of Kyiv. Pripyat is supervised by the State Emergency Service of Ukraine which manages activities for the entire Chernobyl exclusion zone. Following the 1986 Chernobyl nuclear disaster, the entire population of Pripyat was moved to the purpose-built city of Slavutych.

Access to Pripyat, unlike cities of military importance, was not restricted before the disaster as the Soviet Union deemed nuclear power stations safer than other types of power plants. Nuclear power stations were presented as achievements of Soviet engineering, harnessing nuclear power for peaceful projects. The slogan "peaceful atom" (Russian: мирный атом, romanized: mirnyy atom) was popular during those times. The original plan had been to build the plant only 25 km (16 mi) from Kyiv, but the Ukrainian Academy of Sciences, among other bodies, expressed concern that would be too close to the city. As a result, the power station and Pripyat were built at their current locations, about 100 km (62 mi) from Kyiv.

In 1986, the city of Slavutych was constructed to replace Pripyat. After Chernobyl, this was the second-largest city for accommodating power plant workers and scientists in the Commonwealth of Independent States.

One notable landmark often featured in photographs in the city and visible from aerial-imaging websites is the long-abandoned Ferris wheel located in the Pripyat amusement park, which had been scheduled to have its official opening five days after the disaster, in time for May Day celebrations. The Azure Swimming Pool and Avanhard Stadium are two other popular tourist sites.

On 4 February 2020, former residents of Pripyat gathered in the abandoned city to celebrate the 50th anniversary of Pripyat's establishment. This was the first time former residents returned to the city since its abandonment in 1986. The 2020 Chernobyl Exclusion Zone wildfires reached the outskirts of the town, but they did not reach the plant.

During the 2022 Russian invasion of Ukraine, the city was occupied by Russian forces during the Battle of Chernobyl after several hours of heavy fighting. On 31 March Russian troops withdrew from the plant and other parts of Kyiv Oblast. On 3 April Ukrainian troops retook control of Pripyat.
