Pigs of the Roman Empire is an album by the American rock band Melvins and electronic musician Lustmord, which was released in 2004 through Ipecac Recordings.

Adam Jones, guitarist for Tool, also makes substantial contributions to the album.

in 2008, Melvins singer/guitarist King Buzzo remembered: I'd always liked what Lustmord did and I thought that doing a record with him would be a really good thing to do.

But some parts are just me and Dale nearing the end of our tether with Kevin [Rutmanis, Melvins bassist who left the band soon after] and there are things that critics blamed Lustmord for when he's not even on the track!

A double LP edition was released by Alternative Tentacles which lists the ninth track as "??"
