Anne Jaclard, born Anna Vasilyevna Korvin-Krukovskaya (1843–1887), was a Russian socialist and feminist revolutionary. She participated in the Paris Commune and the First International and was a friend of Karl Marx. She was once engaged to Fyodor Dostoyevsky but married the Blanquist Victor Jaclard. Her sister was the mathematician and socialist Sofia Kovalevskaya (1850–1891).
Anna Vasilevna Korvin-Krukovskaya came from a respectable, wealthy military family of aristocratic status. Her father was General Vasily Korvin-Krukovsky. Anna and her sister, the future mathematician Sophia Kovalevskaya, were raised in an enlightened household. As young women they read the materialist literature then popular—books by Ludwig Büchner, Karl Vogt and others—and the writings of 'nihilist' and Narodnik social critics like N.G. Chernyshevsky and P.L. Lavrov. Both women became associated with radical Narodnik circles.
In the 1860s, Anna was briefly engaged to the famous writer Fyodor Dostoyevsky. She met him in 1864, after publishing two stories in his literary journal, The Epoch, unbeknownst to her family. Dostoyevsky respected her talent and encouraged her writing. However, the two were not politically compatible. Although Dostoyevsky had sympathised with utopian socialist ideas in his youth and had even been banished to Siberia for his involvement in the Petrashevsky circle, by the 1860s he was becoming increasingly religious and conservative. The engagement was eventually called off, but Korvin-Krukovskaya and Dostoyevsky remained on friendly terms. It is thought that Dostoyevsky based the character of Aglaya Epanchina in The Idiot on Anna.
