Havok is an American thrash metal band from Denver, Colorado, formed in 2004. As of 2024, their current lineup consists of frontman David Sanchez, drummer Pete Webber, and bassist Nick Schendzielos. They have gone through a number of personnel changes, with each album featuring a different lineup, and leaving Sanchez as the only remaining original member left in the band.

To date, Havok has released five studio albums – Burn (2009), Time Is Up (2011), Unnatural Selection (2013), Conformicide (2017) and V (2020) – and they are currently working on new music. Along with Bonded by Blood, Evile, Hatchet, Municipal Waste and Warbringer, the band has been credited for leading the so-called "thrash metal revival" scene in the late 2000s and early 2010s, and their music has been mostly influenced by the 1980s thrash metal scene as well as the New wave of British heavy metal, death metal, hardcore punk and progressive rock/metal.
