IcedTea is a build and integration project for OpenJDK produced by Red Hat. Its goal is to make it possible to build the OpenJDK with a toolchain consisting entirely of free software. It is the variant of OpenJDK currently distributed with GNU/Linux distributions such as Fedora, Gentoo and Debian.

Red Hat's initial goal with IcedTea was to make the Java OpenJDK software (which Sun Microsystems released as free software in 2007) usable without requiring any other software that is not free software, making it possible to add OpenJDK to Fedora and other Linux distributions that insist on free software. This goal was achieved and a version of IcedTea based on OpenJDK was packaged with Red Hat's Fedora 8 in November 2007. IcedTea has been in active development since, and IcedTea 2.0, based on the final version of Java 1.7, was released in October 2011.
