Open Message Queue (OpenMQ) is an open source message-oriented middleware project by Oracle (formerly Sun Microsystems) that implements the Java Message Service 1.1 API (JMS).

In addition to support for the JMS API, OpenMQ provides additional enterprise features including clustering for scalability and high availability, a C API, and a full JMX administration API. It also includes an implementation of the Java EE Connector Architecture (JCA) called the JMSRA, that allows OpenMQ to be used by a Java EE compliant application server.

OpenMQ is the default JMS provider integrated into GlassFish.

OpenMQ is based on source code donated by Sun Microsystems.

OpenMQ is free software, dual-licensed under two free software licences: the Common Development and Distribution License (CDDL) and the GNU General Public License (GPL) with the classpath exception.
