Power Macintosh（或简称Power Mac、PPC Mac，少部分中文用户以直译称之为：威力麦金塔），是由美商苹果电脑公司（今苹果公司）设计生产的桌面型个人电脑系列产品。

继 Macintosh（麦金塔）系列产品之后，Power Macintosh在90年代中后期是苹果主要的硬件系列产品，机型则因不同的市场定位有：平台式、直立式及含屏幕的一体成型式等各种设计，前期庞大繁杂的产品线并未对提高苹果在个人电脑市占率有所帮助（其高昂的定价以及部分较廉价但品质低劣的授权兼容机，使得一般用户多转而采购一般PC产品），后期机种（1997年贾伯斯返回苹果后）虽然以精简产品线、收回兼容机生产授权、更具创意风格的外形设计、较为大众化的硬件规格等方式力图振作，但仍无法再创Apple II或初期Macintosh般的成功，而贾伯斯也以iPod等消费性电子产品带领苹果走向转型之路。Power Macintosh后为新产品Mac Pro取代。

Power Macintosh, later Power Mac, is a line of Apple Macintosh workstation-class personal computers based on various models of PowerPC microprocessors that were developed, marketed, and supported by Apple Inc. from March 1994 until August 2006. The first models were the Power Macintosh 6100, 7100, and 8100, which offered speeds ranging from 60 to 110 MHz. These machines replaced Apple's Quadra series of personal computers, and were housed in cases very similar to systems sold by Apple up to that point. The Power Mac went on to become the mainstay of Apple's top-end offerings for twelve years, through a succession of case designs, four major generations of PowerPC chips, and a great deal of press coverage, design accolades, and technical controversy. In August 2006, the Power Mac's retirement was announced at Apple's Worldwide Developers Conference by Steve Jobs and Phil Schiller, making way for its Intel-based replacement, the Mac Pro.
