Mutilation or maiming (from the Latin: mutilus) is severe damage to the body that has a subsequent harmful effect on an individual's quality of life.

In the modern era, the term has an overwhelmingly negative connotation, referring to alterations that render something inferior, dysfunctional, imperfect, or ugly.
