The '''Power Mac G4''' is a series of [[personal computer]]s designed, manufactured, and sold by [[Apple Computer]] from 1999 to 2004 as part of the [[Power Macintosh]] line.

This was the first existing Macintosh product to be officially shortened as "Mac" (with the exception of the [[iMac]]), and is the last Mac able to boot into [[classic Mac OS]] with the introduction of [[macOS|Mac OS X]].

The enclosure style introduced with the [[Power Macintosh G3#Blue and White|Power Macintosh G3 (Blue and White)]] was retained through the entire five-year production run of the Power Mac G4, albeit with significant changes to match Apple's evolving industrial design and to accommodate increasing cooling needs.  The G4 and its enclosure were retired with the introduction of the [[Power Mac G5]].
