The SPARC Enterprise series is a range of UNIX server computers based on the SPARC V9 architecture. It was co-developed by Sun Microsystems and Fujitsu, announced on June 1, 2004, and introduced in 2007. They were marketed and sold by Sun Microsystems, Fujitsu, and Fujitsu Siemens Computers under the common brand of "SPARC Enterprise", superseding Sun's Sun Fire and Fujitsu's PRIMEPOWER server product lines. Codename is APL.

The acquisition of Sun Microsystems by Oracle Corporation was completed on January 27, 2010. After the acquisition was completed, Oracle, only a software vendor prior to the merger, owned Sun's hardware product lines, such as SPARC Enterprise, as well as Sun's software product lines, including the Java programming language.
