Samsi River is a large river in The Elder Scrolls III: Morrowind. It is also known as the Ouada Samsi, ouada being another word for 'river.'

The Samsi is located in the West Gash region of Vvardenfell. It is a large waterway whose course creates the peninsula housing both Ald Velothi and Gnisis. Although the shores are very steep and somewhat treacherous to travel or cross, the water itself is not deep enough to permit passage by boat. It flows south and then west, eventually emptying into the Inner Sea.

The Gnisis Eggmine can be accessed directly from the Samsi. Many Dunmer tombs are found in the nearby area.
