A concert tour is a series of concerts by an artist or group of artists in different cities, countries or locations. Often, concert tours are named to differentiate different tours by the same artist and to associate a specific tour with a particular album or product. Especially in the popular music world, such tours can become large-scale enterprises that last for several months or even years, are seen by hundreds of thousands or millions of people, and bring in millions of dollars in ticket revenues. A performer who embarks on a concert tour is called a touring artist.

A concert is a live music performance in front of an audience. The performance may be carried by a single musician, sometimes then called a recital, or by a musical ensemble, such as an orchestra, choir, or band. Concerts are held in a wide variety and size of settings, from private houses and small nightclubs, dedicated concert halls, amphitheatres and parks, to large multipurpose buildings, such as arenas and stadiums. Indoor concerts held in the largest venues are sometimes called arena concerts or amphitheatre concerts. Informal names for a concert include show and gig.
