Java统一表达式语言（英语：Unified Expression Language，简称JUEL）是一种特殊用途的编程语言，主要在Java Web应用进程用于将表达式嵌入到web页面。Java规范制定者和Java Web领域技术专家小组制定了统一的表达式语言。JUEL最初包含在JSP 2.1规范JSR-245中，后来成为Java EE 7的一部分，改在JSR-341中定义。

The Java Unified Expression Language is a special purpose programming language mostly used in Java web applications for embedding expressions into web pages. The Java specification writers and expert groups of the Java web-tier technologies have worked on a unified expression language which was first included in the JSP 2.1 specification (JSR-245), and later specified by itself in JSR-341, part of Java EE 7.
