In entertainment, a tagline (alternatively spelled tag line) is a short text which serves to clarify a thought for, or is designed with a form of, dramatic effect. Many tagline slogans are reiterated phrases associated with an individual, social group, or product. As a variant of a branding slogan, taglines can be used in marketing materials and advertising.

The idea behind the concept is to create a memorable dramatic phrase that will sum up the tone and premise of an audio/visual product, or to reinforce and strengthen the audience's memory of a literary product. Some taglines are successful enough to warrant inclusion in popular culture. Consulting companies which specialize in creating taglines may be hired to create a tagline for a brand or product.
