All-Russian League for Women's Equality (Russian: Всероссийская лига равноправия женщин) was the most important women's organization in the Russian Empire from 1907 to the October Revolution of 1917. It was officially registered on 6 March 1907. Its membership was restricted to women and generally varied between 1,500 and 2,000 members with main branches in Moscow and Saint Petersburg and several smaller regional chapters, including those in Kharkov and Tomsk. It was governed by a 16-member council serving three-year terms. Many former members and leaders of the Union for Women's Equality joined the league, including Zinaida Mirovich, Anna Kalmanovich, , Ariadna Tyrkova-Williams and Jekaterina Shchepkina.
