WTF?! is the seventeenth studio album by German industrial band KMFDM, released on April 26, 2011, on KMFDM Records and Metropolis Records. The regular line-up of Sascha Konietzko, Lucia Cifarelli, Jules Hodgson, Andy Selway, and Steve White was joined by a handful of musicians from other industrial and alternative metal acts. The album took about twice as long as usual for the band to produce, and underwent a significant amount of modification during its recording.

WTF?! reached No. 8 on Billboard's Dance/Electronic Albums chart. Its first single, "Krank", hit No. 15 on the Billboard Singles chart, while its second, "Amnesia", hit No. 3 on the Deutsche Alternative Charts. Critics were generally very positive about the album, and while some felt the album was relatively creative, most felt it stayed close to the same formula the band had used for years.

Band leader Sascha Konietzko first mentioned a new album that would feature "a slew of guest musicians" in March 2010. Former collaborator Bill Rieflin returned to help with WTF?!, and Koichi Fukuda also added guitar work.William Wilson, who had previously performed vocals on "Day of Light", and Free Dominguez, of the group Kidneythieves, were brought in as guest vocalists for one song apiece. In an interview in September 2010, Konietzko said the new album would be named Zilch. A remixed version of "Rebels in Control" was made available on the band's website in December 2010 as a show of support for editor-in-chief Julian Assange, and was streamed more than 75,000 times in two days. The name of the forthcoming album was also revealed to have been changed to WTF?! around the same time.
