Metalogy is a four CD + single DVD boxed set released by heavy metal band Judas Priest in 2004.

The CDs come in card sleeves and are housed in a faux-leather box, which has studs around the center.

The box was re-released in 2008 in a cardboard long-box containing the same 4 CDs as the original release, but not the DVD, which is sold separately.

It was re-released for a second time in September 2013 as a hardback mediabook, again without the DVD.
