A television presenter is a person who introduces or hosts television programs (or segments thereof such as an infomercial advertiser) Nowadays it is common for minor celebrities in other fields to take on this role, but there are also a number of people who have made their name solely within the field of presenting, particularly within children's television series, to become a television personality.

A presenter host or hostess is a person or organization responsible for the running of a public event. A museum or university, for example, may be the presenter or host of an exhibit. In films, a presenter (but not a host) is a usually a well-known executive producer credited with introducing a film or filmmaker to a larger audience. For example: "Presented by Cecil B. DeMille".
