Prima ballerina assoluta is a title awarded to the most notable of female ballet dancers. To be recognised as a prima ballerina assoluta is a rare honour, traditionally reserved only for the most exceptional dancers of their generation. Originally inspired by the Italian ballet masters of the early Romantic ballet, and literally meaning absolute first ballerina, the title was bestowed on a prima ballerina who was considered to be exceptionally talented, above the standard of other leading ballerinas. The title is very rarely used today and recent uses have typically been symbolic, either in recognition of a prestigious international career, or for exceptional service to a particular ballet company. There is no universal procedure for designating who may receive the title, which has led to dispute in the ballet community over who can legitimately claim it. It is usually a ballet company that bestows the title, however some dancers have had the title officially sanctioned by a government or head of state, sometimes for political rather than artistic reasons. Less common is for a dancer to become identified as a prima ballerina assoluta as a result of public and critical opinion.

A ballet dancer is a person who practices the art of classical ballet. Both females and males can practice ballet. They rely on years of extensive training and proper technique to become a part of a professional ballet company. Ballet dancers are at a high risk of injury due to the demanding technique of ballet.
