The Effenaar is a music venue in the centre of Eindhoven, the Netherlands. It was squatted in 1971 and has grown into one of the largest pop venues in the country, hosting rock, pop and techno events. The current Effenaar consists of two music halls after being renovated between 2002 and 2005. The large hall has an audience capacity of 1300, is intended for use by larger bands and acts and is considerably larger than the original hall. The small hall has a capacity of 400 (smaller than the old Effenaar) and is used for smaller and/or regional bands.
The old Effenaar venue hosted many large (national and international) acts throughout its existence, including Bauhaus, Red Hot Chili Peppers and the Sex Pistols. In 2011, the venue celebrated its 40th anniversary with concerts, a book and an exhibition.
