The
Moskva River (,
Moskva-reka), also known as the
Moscow River, is a river of
western Russia. It rises about west of
Moscow, and flows roughly east through the
Smolensk and
Moscow Oblasts, passing through central Moscow. About south east of Moscow, at the city of
Kolomna, it flows into the
Oka River, itself a tributary of the
Volga, which ultimately flows into the
Caspian Sea.
