{{short description|Self-referential paradox}}
The '''Berry paradox''' is a [[self-referential]] [[paradox]] arising from an expression like "The smallest positive integer not definable in under sixty letters" (a phrase with fifty-seven letters).

[[Bertrand Russell]], the first to discuss the paradox in print, attributed it to G. G. Berry (1867–1928),{{sfn|Griffin|2003|p=63}} a junior [[librarian]] at [[University of Oxford|Oxford]]'s [[Bodleian Library]]. Russell called Berry "the only person in Oxford who understood [[mathematical logic]]".{{sfn|Moore|2014|loc=Appendix IV}} The paradox was called "[[Richard's paradox]]" by [[Jean-Yves Girard]].{{sfn|Girard|2011|p=16}}
