Boris Goudenow is a German-language opera composed in 1710 by Johann Mattheson.
The plot concerns intrigues among tsars Feodor I and Boris Godunov and tsarina Irina Godunova, and a cast of Russian, Danish and Swedish nobles.

The manuscript, taken to the Soviet Union at the end of World War II, was discovered in Armenia.
