The Handlebar Club is an association of aficionados of the handlebar moustache, based in London. The club's sole requirement for membership is "a hirsute appendage of the upper lip and with graspable extremities"; beards are absolutely forbidden. The club engages in activism to assuage discrimination against the handlebarred as well as competitive facial hair tourneys, and has inspired the foundation of transatlantic and Scandinavian counterparts. The club declares itself to be at war with a society that demands people choose "the bland, the boring and the generic"; a club chant includes the proposition that being kissed by a smooth face is akin to "meat without the salt".

A handlebar moustache is a moustache with particularly lengthy and upwardly curved extremities. These moustache styles are named for their resemblance to the handlebars of a bicycle. It is also known as a spaghetti moustache, because of its stereotypical association with Italian men. The Handlebar Club humorously describes the style as "a hirsute appendage of the upper lip and with graspable extremities".
