Unbroken is a hardcore band from San Diego, California who have recently re-formed. They were influential in the Southern California hardcore scene during the mid-to-late 1990s. The band chose the name Unbroken because they wanted to emphasize their dedication to the straight edge philosophy of drug abstinence. However, most of the members have since given up this belief.

In 2008, Alternative Press named Unbroken a band of significant interest in its cover story “23 Bands Who Shaped Punk”, citing them as a major influence on hardcore music. Members have also played in Struggle, Swing Kids, Kill Holiday, Julia, Some Girls, Smooth Man Automatic, Johnny Angel, Stabbed By Words, and Over My Dead Body before, during, and after Unbroken’s existence.
