业务流程建模标记法（BPMN, Business Process Modeling Notation）是工作流中特定业务流程的图形化表示法。它由业务流程管理倡议组织（BPMI, Business Process Management Initiative）开发，该组织已于2005年与对象管理组织（OMG, Object Management Group）合并，从那时起，BPMN由OMG维护。BPMN当前版本为1.2，2009年1月发布，有重要修改的2.0版已经进入投票阶段。

Business Process Model and Notation (BPMN) is a graphical representation for specifying business processes in a business process model.

Business Process Management Initiative (BPMI) developed BPMN, which has been maintained by the Object Management Group since the two organizations merged in 2005. Version 2.0 of BPMN was released in January 2011, at which point the name was adapted to Business Process Model and Notation as execution semantics were also introduced alongside the notational and diagramming elements.
