Vasilsursk (Russian: Васильсу́рск) is an urban locality (a work settlement) in Vorotynsky District of Nizhny Novgorod Oblast, Russia, located on the Sura River, not far from its fall into the Volga.

Russians captured it after bloody fight in 1523 from Kuruk Maris and established on its site a small settlement.

Vasilsursk has a humid continental climate (Köppen climate classification Dfb) with long cold winters and warm, often hot dry summers.

[citation needed] In warmer months, a ferry operates between Vasilsursk and the settlement of Lysaya Gora.

During winter, passengers are transported by amphibious boats Khivus-10.
