Phonox is a renowned nightclub located in Brixton, South London, United Kingdom. Opened in September 2015, the venue quickly established itself as a mainstay of the London clubbing scene, with a focus on high-quality sound, expertly curated lineups, and a welcoming, no-nonsense atmosphere. The building that houses Phonox has a rich nightlife legacy, previously operating under various guises including Plan B, which was a popular club in its own right.

When Phonox opened, it marked a complete reinvention both in design and philosophy, stripping back flashy decor in favor of a minimalist, dark interior focused on immersive music experiences. It became well-known for its Martin Audio sound system, crafted for clarity and warmth, and for its resident DJ program, a rarity in London clubs, where Saturday nights were helmed by resident DJs for extended "all night long" sets. This approach fostered a loyal community and a distinctive musical identity centered on underground electronic music, techno, house, disco, and more.

Phonox has earned widespread reputation for its inclusive door policy, excellent acoustics, and forward-thinking bookings, regularly featuring both established and emerging talent. Over the years, the venue has not significantly changed location or structure, but has undergone subtle refurbishments to enhance the dance floor and sound quality, always prioritizing the dance music experience. Its cultural significance lies in bridging local and international talent, serving as a platform for major debuts and intimate headline sets in a city saturated with clubbing history.

Notable artists who have performed at Phonox include international acts such as Peggy Gou, Hunee, Daniel Avery, The Blessed Madonna, Palms Trax, Midland, and Motor City Drum Ensemble, as well as local stars and residents like Jasper James, Artwork, Moxie, Bradley Zero, and ICARUS. The club's programming also regularly features tastemaking selectors like Honey Dijon, Gilles Peterson, Carista, Shanti Celeste, and DJ Seinfield, cementing its status as a vital hub for contemporary dance music culture in London.
