A celebrity is a widely-recognized or famous person who commands a high degree of public and media attention. The word stems from the Latin adjective "celeber" but they may not become a celebrity unless public and mass media interest is piqued.

A small number of celebrities can be considered "global", in that their fame has spread across the world, even across linguistic and cultural boundaries. These celebrities are often prominent political figures, actors, globally successful musicians and sports stars.

The rise of international celebrities in acting and popular music is due in large part to the massive scope and scale of the media industries, enabling celebrities to be viewed more often and in more places. The reach of entertainment products is further extended by large-scale illegal copying of movies and music, which makes inexpensive pirated versions of DVDs and CDs available throughout even less economically developed countries.

Some professional activities, by the nature of being high-paid, highly exposed, and difficult to get into, are likely to confer celebrity status. For example, movie stars and television actors with lead roles on prominently scheduled shows are likely to become celebrities. High-ranking politicians, national television reporters, daytime television show hosts, supermodels, successful athletes and chart-topping pop musicians are also likely to become celebrities. A few humanitarian leaders such as Mother Teresa have even achieved fame because of their charitable work.

While some film and theatre directors, producers, artists, authors, trial lawyers and journalists are celebrities, the vast majority are not, or they garner much less celebrity than their professional importance in the business might seem to warrant.

Individuals with their own television show (or sections of television shows) often become a celebrity, even when their profession would not normally lead to celebrity status: this can include doctors, chefs, gardeners, and conservationists on shows like Trading Spaces and The Crocodile Hunter. However fame based on one program may often prove short-lived after a program is discontinued.
