The Tolstoyan movement is a social movement based on the philosophical and religious views of Russian novelist Leo Tolstoy (1828–1910). Tolstoy's views were formed by rigorous study of the ministry of Jesus, particularly the Sermon on the Mount.

Count Lev Nikolayevich Tolstoy, usually referred to in English as Leo Tolstoy, was a Russian writer. He is regarded as one of the greatest and most influential authors of all time. He received nominations for the Nobel Prize in Literature every year from 1902 to 1906 and for the Nobel Peace Prize in 1901, 1902, and 1909.
