The Royal Barcelona Board of Trade or Chamber of Commerce (Spanish: Real Junta Particular de Comercio, Catalan: Reial Junta Particular de Comerç de Barcelona) was the leading institution for regulating, representing and promoting Catalan commercial and industrial activity in the 18th and 19th century with jurisdiction over the whole Principality of Catalonia. It was created in Barcelona in 1758 and replaced in 1847 by the Provincial Board of Agriculture, Industry and Commerce.
