This article is about a river in Moscow, a tributary of the Moskva River. There are three other Yauza rivers in Central Russia: tributaries of the Lama, Gzhat and Sestra.

The Yauza (Russian:Яуза) is a river in Moscow and Mytishchi, Russia, a tributary of the Moskva River. It originates in the Losiny Ostrov National Park northeast of Moscow, flows through Mytishchi, enters Moscow in the Medvedkovo District and flows through the city in an irregular, meandering, generally north-south direction. The Yauza joins the Moskva River in Tagansky District just west of Tagansky Hill, now marked by the Kotelnicheskaya Embankment tower. Valleys of the Yauza, from the MKAD beltway in the north to the Moscow-Yaroslavl railway west of Sokolniki Park, are protected as natural reserves.
