Power Architecture Platform Reference (PAPR) is an initiative from Power.org to make a new open computing platform based on Power Architecture technology. It follows two previous attempts made in the 1990s, PReP and CHRP.

The PAPR specification provides the foundation for development of standard Power Architecture computers running the Linux operating system. PAPR is Power.org's move toward what IBM did originally with PReP, in that it defines a common hardware definition and software/firmware platform under a set of requirements. In practice, the PAPR is an extension to the Open Firmware specification.

Wind River led the Power.org sub-committee working on an embedded specification known as ePAPR,[1] that was ratified in July 2008. In October 2011, an updated specification was released, the ePAPR v1.1 to clarify and add a new chapter on virtualization.
