A mass tort is a single tort that results in injury to many victims, and therefore involves numerous plaintiffs suing one defendant (or several defendants) who acted negligently. In most mass tort cases, the various individual plaintiffs must be suing based on harms cased by a single common product.
Two of the most frequent mass tort claims concern (1) consumer product claims, in which many plaintiffs might sue together seeking compensation for injury or death caused by dangerous products, and (2) pharmaceutical claims, regarding medical products such as prescribed or over-the-counter drugs and medical devices that are dangerous or even deadly.  Unlike a class action where a lawsuit is filed on behalf of an entire group of people who share a set of unfortunate circumstances, a mass tort or mass action involves a multitude of filings on behalf of each individual in the entire group of people who share the same set of circumstances.
