The Kubnya (Russian: Кубня; Chuvash: Кĕтне, romanized: Kĕtne; Tatar: Гөбенә, romanized: Göbenä) is a river in Chuvashia and Tatarstan, Russian Federation, a left-bank tributary of the Sviyaga.

A major tributary is the Uryum. The maximal mineralization is 500-800 mg/L. The average sediment deposition at the river mouth per year is 92 millimetres (3.6 in). The maximal water discharge is 420 cubic metres per second (15,000 cu ft/s). Drainage is regulated. Since 1978 it is protected as a natural monument of Tatarstan.[2]
