Object-Graph Navigation Language (OGNL), created by OGNL Technology, is an open-source Expression Language (EL) for Java, which, while using simpler expressions than the full range of those supported by the Java language, allows getting and setting properties (through defined setProperty and getProperty methods, found in JavaBeans), and execution of methods of Java classes. It also allows for simpler array manipulation.

It is aimed to be used in J2EE applications with taglibs as expression language.

OGNL is developed now as a part of the OpenSymphony project.

There is also a .NET port of OGNL.
