SWG3 is a renowned multi-disciplinary arts and nightclub venue located in Glasgow, United Kingdom. Originally established in the early 2000s, SWG3 began its life as an industrial warehouse in Glasgow's Finnieston district, a historically working-class area that has since transformed into one of the city's most vibrant cultural quarters. Over the years, SWG3 has expanded its remit from contemporary art and exhibition space to include a wide range of live music events, club nights, and immersive experiences.

The venue is celebrated for its raw, industrial aesthetic, with multiple spaces including the main warehouse, the TV Studio, The Poetry Club, and expansive outdoor areas. SWG3's reputation is built on its eclectic programming and its role as an incubator for both local talent and international superstars, reflecting the diverse and progressive spirit of Glasgow itself. The venue has been recognized as a key player in the city’s nightlife scene and a pillar of Scotland’s broader creative landscape, contributing to Glasgow's status as a UNESCO City of Music.

While the building itself has remained in the same location, SWG3 has undergone significant structural and organizational changes—including expansions, renovations, and sustainability initiatives like the pioneering BODYHEAT energy project aimed at reducing its carbon footprint. Through its evolution, SWG3 has maintained its commitment to inclusivity, creativity, and community engagement, solidifying its position as a flagship destination for arts and entertainment in the UK. Notable artists who have performed at SWG3 include international acts such as Peggy Gou, Bicep, LCD Soundsystem, Aphex Twin, The Chemical Brothers, and Nile Rodgers, alongside celebrated local talent like Denis Sulta, Slam, Optimo, Sub Club residents, and Scottish voices such as Lewis Capaldi and Mogwai.
