The
Yenisei (,
Yenisey, ), 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.
