Q2K is the seventh studio album by progressive metal band Queensrÿche, released on 14 September 1999. It was the only Queensrÿche studio album to feature guitarist Kelly Gray, who, in the early 1980s, was in a band called Myth with vocalist Geoff Tate. "Breakdown" was released as the first single off Q2K.
Rhino Entertainment, Queensrÿche's current label, purchased Q2K from Atlantic Records and re-released it with bonus tracks.
In Canada, the album was released by Anthem Records, also the Canadian home label to fellow Atlantic act Rush.
