Unbroken is a metallic hardcore band from San Diego County, California. 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 an influence on later groups such as The Hope Conspiracy, Suicide File, Planes Mistaken for Stars, Modern Life Is War, and Bleeding Through.
