Esta página lista os livros mais vendidos, tanto os volumes singulares quanto as séries literárias, de todos os tempos e em qualquer língua. "Mais vendidos" refere-se ao número estimado de cópias vendidas por cada livro, ao invés do número de livros impressos ou possuídos atualmente. Histórias em quadrinhos e livros didáticos não estão incluídos na lista. Os livros estão listados de acordo com a maior estimativa de vendas como relatado em fontes fiáveis e independentes. A lista é incompleta por excluir vários livros, como Dom Quixote, Um Conto de Duas Cidades, Os Três Mosqueteiros, Os Miseráveis, Orgulho e Preconceito, Alice no País das Maravilhas e Odisseia, que são comumente citados como "livros mais vendidos" mas que ainda assim não possuem números de vendas confiáveis.
De acordo com o Livro Guinness dos Recordes, a Bíblia é o livro mais vendido de todos os tempos com mais de 5 bilhões de cópias vendidas e distribuídas. Entretanto, o livro Citações do Presidente Mao Tsé-Tung, também conhecido como "O Livro Vermelho", possui cifras de vendas e distribuição diversas, com algumas fontes reivindicando mais de 6,5 bilhões de cópias impressas, e outras citando "mais de um bilhão" de cópias oficiais entre 1966 e 1969 apenas, além de "incontáveis reimpressões locais e traduções não-oficiais." O Alcorão também é amplamente divulgado como um dos livros mais vendidos e impressos de todos, com bilhões de cópias supostamente existentes. Cifras exatas de impressão para esses e outros livros são inexistentes ou não confiáveis, já que esses tipos de livros são publicados por editoras diferentes e não relacionadas, em alguns casos no decorrer de vários séculos. Todos os livros de natureza religiosa, ideológica, filosófica ou política foram excluídos desta lista por estas razões.
A série Perry Rhodan vendeu mais de 1 bilhão de cópias, mas não foi incluído porque a lista também apresenta vendas de revistas pulp, não novelas por si só. Igualmente, a série de Jerry Cotton vendeu mais de 300 milhões de cópias, mas a maioria das vendas foi no formato de revista.
O Senhor dos Anéis por J.R.R. Tolkien não foi incluído porque foi escrito por Tolkien como um livro único.
Os valores apresentados para alguns livros são referentes ao número de cópias impressas e não ao número de vendas oficiais.

↑The Lord of the Rings is considered by most people to be a single book, because it was written and planned by the author to be such. It is written in the preface to many editions that the book is sometimes 'erroneously' referred to as a trilogy, and goes on to state that it is one book in three volumes. Some people consider it to instead be a trilogy or series of three books, because it was originally published as a series of three volumes: The Fellowship of the Ring, The Two Towers, and The Return of the King. Lord of the Rings, Waterstones.com: This move by the publishing house was due largely to post-war paper shortages as well as to minimize the price of the first volume to aid sales.
Wagner, Vit. "Tolkien proves he's still the king", The Toronto Star, 16 April 2007: In subsequent printings the book has sometimes appeared as a single volume, and in at least one case was split into seven.
