Ubort River (Russian:Уборть) is a river in Zhytomyr Oblast (Ukraine) and Homiel Voblast (Belarus), a right tributary to the Pripyat River, in the Dnieper river basin.

The Ubort River is fed mostly by snow melt (~70%), and peaks during the Spring run-off, usually mid March to early May, and maintains an even, albeit lower, flow during the summer months. It can freeze up as early as mid November or as late as January, and the ice breaks up as early as mid February or as late as mid April. It was contaminated during the Chernobyl disaster.
