Mulennium is a live album by American southern rock band Gov't Mule.

It includes all three sets from the band's December 31, 1999/January 1, 2000 New Year's Eve show at the Roxy Theatre in Atlanta, Georgia.

"Bad Little Doggie" begins the set, as many Mule shows have over the years, with the stage introduction by Kirk West, longtime Allman Brothers Band roadie and "tour mystic".

West's introduction was in keeping with the theme of North Georgia shows, Athens, Macon and Atlanta as the 'best cup of coffee'.

Warren played slide guitar to usher in the new Millennium using his vocal mic stand in place of a Coricidin medicine bottle.
