The Evolution of Chaos is the third studio album by American thrash metal band Heathen.

It was released in Japan on December 23, 2009 via King Records, January 25, 2010 in Europe, and on March 31, 2010 in the US via Mascot Records.

Heathen had recorded The Evolution of Chaos in 2008 and was originally scheduled for release on July 20, 2009, but was pushed back to late 2009 as more time was needed to complete the mixing process.

Metal Rules gave the album a perfect five out of five, calling it an "absolute masterpiece of modern thrash" and "flawless in almost every way".
