Odditorium or Warlords of Mars is the fifth studio album by American rock band The Dandy Warhols.

The album is a return to the psychedelic, guitar-based sound of the group's earlier records, following their foray into a new wave style with 2003's Welcome to the Monkey House.

Bandmember Zia McCabe worked on the album during a pregnancy with her first child, Matilda Louise, and gave birth only a week after its completion.

"[13] Trouser Press wrote: "Odditorium is the Dandys' magnum opus, a sprawling, rambling but somehow coherent result of the ambitions developed on previous albums".

"[11] Pitchfork gave the album an exceptionally low 1.2/10 rating, writing "only the truly earless would mistake this assortment of bloated in-jokes and interminable, sub-song drones for some kind of masterpiece.
