1. Anne Frank: *The Diary of a Young Girl*
2. Samuel Pepys: *The Diary of Samuel Pepys*
3. Virginia Woolf: *The Diary of Virginia Woolf* (though she actually called it her "journal")
4. Leo Tolstoy: *The Diary of Leo Tolstoy*
5. Sylvia Plath: *The Bell Jar* (though it's a semi-autobiographical novel, it draws heavily from Plath's journal entries)
These are just a few examples, and there are many other famous diarists throughout history!
