Debaser, Concert venue in Hornstull Strand, Stockholm, Sweden

Debaser is a rock club that since 2019 has operated only at Hornstulls Strand in Stockholm, in a venue under the street above. It has no dining complex; it is a single performance space for small and medium-sized bands, with a stage and standing audience area.

Debaser opened in September 2002 in a space beneath the Slussen cloverleaf interchange, founded by Annelie Telford and Jocke Jonsson. A second venue, Debaser Medis, opened on 1 September 2006 in Medborgarhuset at Medborgarplatsen, in premises previously occupied by the club Mondo. Debaser Malmö followed on 3 May 2007 in Inkonst's former rooms by Folkets Park. Slussen closed in 2013 for the Slussen reconstruction, Malmö closed the same year, and Medis held its last open night on New Year's Eve 2016.

The venue has become rooted in the local music culture and regularly draws emerging and established artists who perform before audiences of varying ages. The events create a meeting point where music and dining come together, turning the location into a social hub for the neighborhood.

The complex sits directly on the waterfront and is easily accessible by public transportation. Visitors should note that most evenings enforce an 18-year age requirement, though exceptions exist for younger people accompanied by adults.

Debaser takes its name from the Pixies song "Debaser". Ebba Grön's temporary, spontaneous reunion at the Joe Strummer tribute happened at Debaser Slussen in 2003, and Bob Dylan gave an unannounced, widely reported set at Debaser Medis in 2007.
