Arnold's Problems is a book edited by Soviet mathematician Vladimir Arnold, containing 861 mathematical problems from many different areas of mathematics.
The book was based on Arnold's seminars at Moscow State University.
The problems were created over his decades-long career, and are sorted chronologically (from the period 1956–2003).
It was published in Russian as Задачи Арнольда in 2000, and in a translated and revised English edition in 2004 (printed by Springer-Verlag).
The book is divided into two parts: formulations of the problems, and comments upon them by 59 mathematicians.
