Alexander Louis Texeira de Mattos ("Texeira" often spelled "Teixeira") was a literary critic and publisher, who gained his greatest level of fame as a translator.

Born in 1865, he was responsible for many extremely perceptive and well-executed English translations of major French- and Dutch-language literary works, including works by Emile Zola, Maurice Maeterlinck, Alexis de Tocqueville, Jean Henri Fabre, Maurice Leblanc, Gaston Leroux and Louis Couperus. The high quality and readability of his work was such that many of his translations are still in print today; although some of these are over a century old, they have yet to be superseded by a more modern version. He died in 1921.
