Tweekend is the second studio album by American electronic music duo the Crystal Method, released on July 31, 2001, by Outpost Recordings and Geffen Records.

The album title is derived from the demise of the West Coast rave scene in the late 1990s and 2000s.

Tweekend debuted at number 32 on the Billboard 200 in the United States, Crystal Method's highest position on that chart in their history.

It also debuted at number 6 on the Canadian Albums Chart, selling 9,603 copies in its first week.

Note: Alternate versions of this album have "Murder" and "Over the Line" switched around.
