Personal injury is a legal term for an injury to the body, mind, or emotions, as opposed to an injury to property. In common law jurisdictions the term is most commonly used to refer to a type of tort lawsuit in which the person bringing the suit has suffered harm to their body or mind. Personal injury lawsuits are filed against the person or entity that caused the harm through negligence, gross negligence, reckless conduct, or intentional misconduct, and in some cases on the basis of strict liability. Different jurisdictions describe the damages in different ways, but damages typically include the injured person's medical bills, pain and suffering, and diminished quality of life.

A work accident, workplace accident, occupational accident, or accident at work is a "discrete occurrence in the course of work" leading to physical or mental occupational injury. According to the International Labour Organization (ILO), more than 337 million accidents happen on the job each year, resulting, together with occupational diseases, in more than 2.3 million deaths annually.
