Reputation of a social entity (a person, a group of people, an organization) is an opinion about that entity, typically a result of social evaluation on a set of criteria. It is important in education, business, and online communities.

Reputation may be considered as a component of identity as defined by others.

Reputation is known to be an ubiquitous, spontaneous and highly efficient mechanism of social control in natural societies. It is a subject of study in social, management and technological sciences. Its influence ranges from competitive settings, like markets, to cooperative ones, like firms, organisations, institutions and communities. Furthermore, reputation acts on different levels of agency, individual and supra-individual. At the supra-individual level, it concerns groups, communities, collectives and abstract social entities (such as firms, corporations, organizations, countries, cultures and even civilizations). It affects phenomena of different scales, from everyday life to relationships between nations. Reputation is a fundamental instrument of social order, based upon distributed, spontaneous social control.

Joan Jett (born September 22, 1958) is an American rock guitarist, singer, songwriter, producer and occasional actress., best known for her work with Joan Jett & the Blackhearts, including their hit cover "I Love Rock 'n' Roll", which was No. 1 on the Billboard Hot 100 from March 20 to May 1, 1982, as well as for their other popular recordings including "Crimson and Clover", "I Hate Myself for Loving You", "Do You Want to Touch Me", "Light of Day", "Love Is All Around", "Bad Reputation".

Her musical and songwriting approach is heavily influenced by the hard-edged, hard beat-driven rhythms common to many rock bands of her native Philadelphia,^{[citation needed]} often featuring lyrics surrounding themes of lost love, criticisms of insincerity, the quest for authenticity, as well as the struggles and resolutions of the American middle class. She has three albums that have been certified Platinum or Gold, and she has been referred to as the "Queen of Rock 'n' Roll" many times during her career.
