可视化编程语言（Visual programming language，以下简称VPL），又称『图形化编程语言』、『可视化程序编成语言』。系用户利用图形化元素进行编程；相异于文本式编程。VPL以视觉表达为基础，利用『文法』或是某种『辅助标记』进行图形与文本的排列。许多VPL建基于『方块与箭头』的概念之上，以方块或屏幕上的对象为本体，以箭头相连接，以直线段与弧线段代表相互之间的关系。

更进一步的分类VPL，依据类别与视觉表达延伸的使用，分为：图标式编程语言、表格式编程语言以及图表式编程语言。可视化编程环境（Visual programming environments）提供图形与图标的元素让用户操弄，以便符合特定空间文法以进行程序建构。

In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs (known as dataflow or diagrammatic programming) are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.
