The Seym or Seim (Russian: Сейм; Ukrainian: Сейм) is a river that flows westward in Russia and Ukraine. It is 748 kilometres (465 mi) long (250 km within Ukraine) and its basin area about 27,500 square kilometres (10,600 sq mi). It is the largest tributary of the Desna.^[2][3][1][4]

Places on the river include Kursk, Kurchatov,^{[citation needed]} Rylsk, Glushkovo,^[5] Putyvl, Baturyn, and the junction with the Desna, which continues west and south past Chernihiv to Kyiv.^{[citation needed]}

In September 2024, during the Russian invasion of Ukraine, Ukrainian officials accused Russia of polluting the river by dumping sewage from a sugar factory in Tyotkino, Kursk Oblast, resulting in environmental damages estimated at about Hr 186 million ($4.5 million) in Chernihiv Oblast that included a decrease in oxygen levels and fish kills downstream.^[6]
