Hordes of Chaos is the twelfth studio album by German thrash metal band Kreator, released in 2009.

Frontman Mille Petrozza noted that this was the first time they had recorded an album this way since Pleasure to Kill in 1986.

[6] Hordes of Chaos also marked the first time since its inception that Kreator had not changed their lineup after at least two albums.

The standard edition was issued in a jewel case and featured the 10 album tracks.

It featured new artwork, extended liner notes by Joel McIver, promo videos, a bonus disc with demo tracks and cover songs and various pieces of memorabilia (such as a photobook, sticker, poster and photo card).
