A chiringuito (also known by other nicknames in Spanish; in Catalan called a "guingueta", or, by influence of Spanish, a "xiringuito") is a small enterprise, usually a bar, selling mainly drinks and tapas, and sometimes meals, in a more or less provisional building, often on a beach or loose surface where a more permanent structure may be inviable.

Since many "chiringuito" bars tend (or tended) to operate in the informal sector of the economy, the term is sometimes extended to any dodgy business activity or company that operates in loosely regulated grey markets or the unlawful black market sector.
