A celebrity chef is a kitchen chef who has become a celebrity. Today, chefs often become celebrities by presenting cookery advice and demonstrations, usually through the media of television and radio, or in printed publications. While television is ultimately the primary way for a chef to become a celebrity, some have achieved this through success in the kitchen, cookbook publications, and achieving awards such as Michelin stars, while others are home cooks who won competitions. In South Korea, a celebrity chef is referred as a cheftainer.

A chef is a professional cook and tradesperson who is proficient in all aspects of food preparation, often focusing on a particular cuisine. The word "chef" is derived from the term chef de cuisine, the director or head of a kitchen. Chefs can receive formal training from an institution, as well as by apprenticing with an experienced chef.
