Nizhyn (Ukrainian: Ніжин, pronounced [ˈn⁽ʲ⁾iʒɪn] ; Russian: Нежин) is a city located in Chernihiv Oblast of northern Ukraine along the Oster River. The city is located 116 km (72 mi) north-east of the national capital Kyiv. Nizhyn serves as the administrative center of Nizhyn Raion. It hosts the administration of Nizhyn urban hromada which is one of the hromadas of Ukraine and was once a major city of the Chernigov Governorate. Nizhyn has a population of 65,830 (2022 estimate).

The earliest known references to the location go back to 1147, when it was briefly mentioned as Unenezh.

In the times of the Polish–Lithuanian Commonwealth, Nizhyn was granted Magdeburg rights (1625) as a self-governing town. In 1663, Nizhyn was the place of the Black Council of Ukrainian Cossacks, which elected Bryukhovetsky as the new Hetman of the Zaporizhian Host thus conditionally dividing Ukraine (Cossack Hetmanate) into left-bank Ukraine and right-bank Ukraine. It was also the seat of a major Cossack regiment (until 1782).

In the Cossack Hetmanate, Nizhyn had six voivodes (a Muscovite military position) from 1665 to 1697. The voivodes of the city were Ivan Rzhevskiy (1665–1672), Stepan Khruscheov (1672–1673), Prince Vladimir Volkonskiy (1673–1675), Prince Semeon Zvenigorodskiy (1673–1675), Avraam Khitrovo (1689–1692), and Ivan Saveolov Junior (1692–1697).

Nizhyn was once a major center of Hasidic Judaism and is the site of the Ohel (tomb) of the Hasidic master, Rabbi Dovber Schneuri of Chabad-Lubavitch. The city also housed the thriving Greek community, which enjoyed a number of privileges granted by Bohdan Khmelnytsky.

In the 19th century Nizhyn became an uyezd capital of the Chernihiv Governorate and the biggest city in the guberniya. In 1805, the Bezborodko Lyceum was established there (today — Nizhyn Gogol State University); its graduates include Nikolai Gogol whose statue graces one of city streets as well as Yevhen Hrebinka among other graduates. Nizhyn has also long been noted for its famous cucumbers.

During World War II, Nizhyn was occupied by the German Army from 13 September 1941 to 15 September 1943.

Jews first settled in Nizhyn at the beginning of the 19th century after the partition of Poland. The town grew to become a center for the Chabad Hasidim of Ukraine. Dovber Schneuri, the second Chabad rebbe, is buried here. By 1847, 1,299 Jews had registered as residents. In 1897, 24% of the population, or 7,361 residents, were Jewish.

A wave of pogroms severely affected the Jewish population in 1881 and 1905. One group of emigrants settled in Philadelphia and founded the Neziner Congregation in 1896.

During their retreat from the Germans in the spring of 1918, the Red Army carried out additional pogroms. During World War II, the region was occupied by Germany, who murdered all Jews in the area. Only those who escaped survived.

In 1959, 1,400 Jews lived in Nizhyn, about 3% of the town's population. In 2005, Nizhyn population reached 80,000. Only about 300 Jewish families lived in the city.

In July 1969 two Tupolev Tu-22 aircraft from the nearby air base collided in mid-air. The crew ejected and the plane flew on unpiloted for 52 minutes, threatening the city of Nizhyn before crashing 0.5 km from the city's railway station.

The city of Nizhyn is one of the ancient cities of Ukraine. The architectural complex of the city forms an expressive ensemble of an ancient trade city. The experts' estimates distinguish more than 300 ancient buildings, where 70 are of a great cultural and historical value. The expressive 200 years ensemble of Post Station (the only one preserved in Ukraine) deserves special mention. Nizhyn is a city of students (each fifth inhabitant of Nizhyn is a student). The following educational establishments operate in Nizhyn – State University named after Gogol; Agro-technical College, faculty of Kremenchyk Institute of Economy and New Technologies, College of Culture and Arts named after Zankovetska, Medical College, Nizhyn Professional Lyceum of Services, Nizhyn Agrarian Lyceum, vocational college, Lyceum at the university. There are four club institutions, the Drama Theater named after Kotsiubynskyi, the Choreographic school and park landscapes in the city.

It is included into the tour “Necklace of Slavutych”.

A postage stamp featuring the coat of arms of Nizhyn was released by Ukraine in 2017.

Until 18 July 2020, Nizhyn was designated as a city of oblast significance and did not belong to Nizhyn Raion even though it was the center of the raion. As part of the administrative reform of Ukraine, which reduced the number of raions of Chernihiv Oblast to four, the city was merged into Nizhyn Raion.

Architecturally Nizhyn was shaped in the 18th century. Foremost among its buildings must be mentioned its seven Baroque churches: Annunciation Cathedral (1702–16, modernised 1814), Presentation Cathedral (1788), St. Michael's Church of the Greek community (1719–29), St John's Church (1752, illustrated, to the right), Saviour's Transfiguration Church (1757), Intercession Church (1765), and the so-called Cossack Cathedral of St. Nicholas (1658, restored 1980s), a rare survival from the days of Nizhyn's Cossack glory, noted for its octagonal vaults and drums crowned by archetypal pear-shaped domes. Other notable buildings include the Trinity Church (1733, rebuilt a century later), the Greek magistrate (1785), and the Neoclassical complex of the Nizhyn Lyceum (designed by Luigi Rusca, built in 1805–17, expanded in 1876–79).

There is the memorial museum of Russian naval officer and explorer Yuri Lisyansky in his family house [uk] in Nizhyn and a monument by the house.
