The Yenisei (Russian: Енисе́й, Jenisej; Mongolian: Енисей мөрөн, Yenisei mörön); Buryat: Горлог мүрэн, Gorlog müren; Tyvan: Улуг-Хем, Ulug-Khem; Khakas: Ким суг, Kim sug also Romanized Yenisey, Enisei, Jenisej, is the largest river system flowing to the Arctic Ocean. It is the central of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Lena). Rising in Mongolia, it follows a northerly course to the Yenisei Gulf in the Kara Sea, draining a large part of central Siberia, the longest stream following the Yenisei-Angara-Selenga-Ider river system.

The maximum depth of the Yenisei is 24 metres (80 ft) and the average depth is 14 metres (45 ft). The depth of river outflow is 32 metres (106 ft) and inflow is 31 metres (101 ft).

The river flows through Tuva, Khakassia, and the city of Krasnoyarsk.

Its tributaries include the Angara, Nizhnyaya Tunguska, and Tuba rivers.

The 320-kilometre (200 mi), partly navigable Upper Angara River feeds into the northern end of Lake Baikal from the Buryat Republic but the largest inflow is from the Selenga which forms a delta on the south-eastern side.
