In [[computer science]], a '''dynamic programming language''' is a class of [[high-level programming language]]s, which at [[Runtime (program lifecycle phase)|runtime]] execute many common programming behaviours that [[Static program analysis|static programming languageslanguage]]s perform during [[Compiler|compilation]]. These behaviors could include an extension of the program, by adding new [[Source code|code]], by extending [[Object (computer science)|objects]] and definitions, or by modifying the [[type system]]. Although similar behaviors can be emulated in nearly any language, with varying degrees of difficulty, complexity and performance costs, dynamic languages provide direct tools to make use of them. Many of these features were first implemented as native features in the [[Lisp (programming language)|Lisp]] programming language.

Most dynamic languages are also [[Dynamic typing|dynamically typed]], but not all are. Dynamic languages are frequently (but not always) referred to as [[scripting language]]s, although that term in its narrowest sense refers to languages specific to a given run-time environment.
