The Muscovite-Lithuanian Wars, also known as the Russo-Lithuanian Wars, or just either Muscovite Wars or Lithuanian Wars, are a series of wars between the Grand Duchy of Lithuania, allied with the Kingdom of Poland, and Grand Duchy of Moscow.

After several defeats at the hands of Ivan III and Vasily III, the Lithuanians are increasingly reliant on Polish aid, which eventually becomes an important factor in the creation of the Polish-Lithuanian Commonwealth.

In the first series of wars in the fifteenth century, the Lithuanians will gain control of a lot of Rus' territories, from Kiev to Mozhaisk.

The Russo-Swedish War of 1495–1497 is a result of an alliance between Ivan III of Russia and Hans of Denmark, who is waging war against the Sture family of Sweden in the hope of regaining the Swedish throne.

It is believed that Hans promised to concede some stretches of Finnish lands to the Russian monarch, although he does not bother to honor the agreement after he has been crowned King of Sweden at the close of the war.
