The Asociación Catalana de Locales de Alterne (English: Catalan Association of Alternate Premises) (ACLA) is an association of businessmen in the prostitution sector in Catalonia, Spain. The association was created in 2002 and represents 40 clubs out of the 450 in Catalonia. Its main activities focus on lobbying legislators to create a regulatory framework to regulate activities within the prostitution sector and to modify Barcelona's restrictive legislation on sex clubs. They criticise the lack of action on what they consider to be the main problem of non-regulation: street prostitution.
