Boyhood is a novel first published in 1854 by Russian author Leo Tolstoy.

It is the second in Tolstoy's trilogy of three autobiographical novels, including Childhood and Youth, published in a literary journal during the 1850s. 

Count Lev Nikolayevich Tolstoy; (1828-1910), also known as Leo Tolstoy, was a Russian writer who primarily wrote novels and short stories. Tolstoy was a master of realistic fiction and is widely considered one of the world's greatest novelists. He is best known for two long novels, War and Peace (1869) and Anna Karenina (1877).

Tolstoy is one of the giants of Russian literature. His contemporaries paid him lofty tributes. Fyodor Dostoyevsky thought him the greatest of all living novelists. Later critics and novelists continue to bear testament to Tolstoy's art. Virginia Woolf declared him the greatest of all novelists. James Joyce noted that, "He is never dull, never stupid, never tired, never pedantic, never theatrical!". Thomas Mann wrote of Tolstoy's seemingly guileless artistry: "Seldom did art work so much like nature".
