Xserve是苹果电脑所出品的机架式服务器，使用Mac OS X Server操作系统。

当Xserve在2002年发表时，它是苹果电脑在1996年的Apple Network Server之后第一次的服务器硬件设计。它最早包含一或二颗PowerPC G4处理器，但后来转换为新的Power PC G5，随后再次转换为两颗四核心的Intel「Nehalem核心架构」处理器。Xserve可作多种应用，包括文件服务器，网页服务器，甚至是以集群技术运行高性能计算应用－Xserve集群，也提供不包含显卡与光驱的Xserve集群节点。

Xserve was a line of rack unit computers designed by Apple Inc. for use as servers. When the Xserve was introduced in 2002, it was Apple's first designated server hardware design since the Apple Network Server in 1996. (In the meantime, ordinary Power Macintosh G3 and G4 models were rebranded as Macintosh Server G3 and Macintosh Server G4 with some alterations to the hardware, such as added Gigabit Ethernet cards, UltraWide SCSI cards, extra large and fast hard drives etc. and shipped with Mac OS X Server software.) It initially featured one or two PowerPC G4 processors, but was later switched over to the then new PowerPC G5, and subsequently switched again to two quad-core Intel Nehalem microprocessors.
