A talk show (American and Australian English) or chat show (British) is a television program or radio program where one person (or group of people) discuss various topics put forth by a talk show host.

Sometimes, talk shows feature a panel of guests, usually consisting of a group of people who are learned or who have great experience in relation to whatever issue is being discussed on the show for that episode. Other times, a single guest discusses their work or area of expertise with a host or co-hosts. A call-in show takes live phonecalls from callers listening at home, in their cars, etc. Sometimes, guests are already seated but are often introduced and enter from backstage. Gay Byrne, Steve Allen, Jack Paar, Johnny Carson,, Dick Cavett, Ed Sullivan, Oprah Winfrey, Rush Limbaugh, and Mosunmola Abudu have hosted notable talk shows; in many cases, the shows have made their hosts famous.

Television talk shows often feature celebrity guests who talk about their work and personal lives as well as the their latest films, TV shows, music recordings or other projects they'd like to promote to the public. The hosts are often comedians who open the shows with comedy monologues.
