The Battle of the Neva is fought between the Novgorod Republic and Swedish armies on the Neva River, near the settlement of Ust-Izhora, on July 15, 1240.

The purpose of the Swedish invasion is probably to gain control over the mouth of the Neva and the city of Ladoga and, hence, seize the most important part of the Trade Route from the Varangians to the Greeks, which has been under Novgorod's control for more than a hundred years.

The battle is part of the medieval Swedish-Novgorodian Wars.
