A boy band (or boyband) is loosely defined as a vocal group consisting of young male singers, usually in their teenage years or in their twenties at the time of formation, singing love songs marketed towards young females. Being vocal groups, most boy band members do not play musical instruments, either in recording sessions or on stage, making the term something of a misnomer. However, exceptions do exist. Many boy bands dance as well as sing, usually giving highly choreographed performances.

A boy is a human male child or young man.
