Ichnia (Ukrainian: Ічня, pronounced [ˈitʃnʲɐ]) is a small city in Pryluky Raion, Chernihiv Oblast, Ukraine, located on the Ichenka River. It hosts the administration of Ichnia urban hromada, one of the hromadas of Ukraine. Population is 10,390 (2022 estimate).

There is evidence that in ancient times there was a small settlement called Yaskove, which was destroyed by the Mongol-Tatars. The city got its name from the name of the river Ichen, and the name of the river itself was transformed into the affectionate form of Ichenka. Researchers associate the name of the river with Tatar ichen 'watering hole', 'parking for horses'.

The first information about Ichnia dates back to the 14th century. From the 14th to 16th centuries, it was ruled by the Grand Duchy of Lithuania and the Polish–Lithuanian Commonwealth.

In the middle of the 16th century, Ichnia was granted with the status of a market town. In 1666, a town hall was built. Probably at this time, the Ichnia's castle was built. Residents of the city participated in the struggle against the Swedish army of Charles XII of Sweden during the Great Northern War.

In 1748, Ichnia's 20 households belonged to Knyaz N. Saakadze, and 119 households - Colonel from Pryluky G. Galagan. The town had a distillery, 6 water mills, and a brickyard.

In 1894, the town was included into a local railroad connection. In 1897, there were four stone churches. The town operated a post office, hospital, rural and ministerial school, and library.

In 1957, Ichnia received the status of a town.

Nowadays, the leading industry in Ichnia is the food industry (alcohol, tobacco, feed mill, canning, and cheese-milk powder).

In October 2018, Ichnya became an epicenter of massive fire following an explosion at the munitions depot of the 6th Arsenal (military unit A-1479).
