Paisius Yaroslavov (Russian: Паисий Ярославов; died 1501) was the most famous monk of the Kamenny Monastery, located by Lake Kubenskoye in Vologda Oblast, Russia.
He also wrote O vtorom brake velikogo knyazya Vasiliya (О втором браке великого князя Василия, "On the Second Marriage of Grand Prince Vasili"), which provides valuable information on the role of different clergymen in the marriage and also contains messages from four ecumenical patriarchs and monks from Mount Athos.
Together with his closest associate, Nilus of Sora, Paisiy Yaroslavov enjoyed extraordinary respect, both among the contemporary Russian hierarchy and from the grand prince.
In 1489, Gennady of Novgorod, entering into a struggle with the local Sect of Skhariya the Jew and reporting them to the Rostov archbishop, asked the latter to consult Paisiy Yaroslavov and Neil Sorsky, who lived within his diocese, and attract them to the fight: it was about rumors spread among the people about the near demise of the world.
According to contemporaries, both elders “for the sake of a strong residence and virtue of the multitude had great daring to the Sovereign and were zealously acceptable and revered by him".
