The '''Obsha''' ({{Langx|ru|Обша}}) is a [[river]] in [[Sychyovsky District]] of [[Smolensk Oblast]] and [[Oleninsky District|Oleninsky]], [[Belsky District, Tver Oblast|Belsky]], and [[Zharkovsky District]]s of [[Tver Oblast]]s, [[Russia]]. It is a left [[tributary]] of the [[Mezha (Daugava)|Mezha]] ([[Daugava|Western Dvina]] [[drainage basin|basin]]). The Obsha is {{convert|153|km|mi}} long, and the area of its basin {{convert|2080|km2|sqmi}}.<ref name="GSE"/> The town of [[Bely, Tver Oblast|Bely]] is located on the banks of the Obsha.

The Obsha River originates in the northwestern area of Sychyovsky District. It flows initially to the north, then turns westward as it enters Tver Oblast. Along its course, it serves as the boundary between Smolensk and Tver Oblasts for a section. Moving further, it passes through the southern region of Oleninsky District, and a brief segment of the Obsha forms part of the border between Oleninsky and Belsky Districts. Downstream of the village of [[Antipino, Tver Oblast|Antipino]] it departs from the border and flows southwest, through the town of Bely. In Bely, it turns northwest and crosses into Zharkovsky District. The mouth of the Obsha is located by the village of [[Ustye, Zharkovsky District, Tver Oblast|Ustye]].

The [[drainage basin]] of the Obsha includes almost the entire Belsky District, as well as minor areas in the west of Sychyovsky District, in the south of Oleninsky District, in the northeast of Zharkovsky District, and in the north of [[Kholm-Zhirkovsky District]] of Smolensk Oblast.
