'''Mac OS Runtime for Java''' ('''MRJ''', originally '''Macintosh Runtime for Java''') was [[Apple Inc.|Apple's]] proprietary [[Java Virtualvirtual Machinemachine|virtual machine]] for [[Java (programming language)|Java-based]] applications in the [[classic Mac OS]] (i.e. versions prior to [[Mac OS X]]). Both a runtime environment and a [[software development kit]] (SDK) are available.

The runtime environment includes a [[Just-in-time compilation|JIT compiler]] developed by [[NortonLifeLock|Symantec]], the standard Java [[class library]] from [[Sun Microsystems|Sun]], additional classes providing Macintosh-specific functionality, and the Apple Applet Runner (a lightweight application for running Java [[applet]]s without the overhead of a [[web browser]]). A number of web browsers could use MRJ to run Java applets in web pages, including [[Microsoft]] [[Internet Explorer]], [[iCab]] and [[HotJava]].
