The Incorporated Company of Hostmen of Newcastle upon Tyne, often called the Hostmen's Company of Newcastle, is a company incorporated by royal charter of 22 March 1599/1600. Analogous to a livery company of the City of London, it still exists. It is best known to economic historians as a cartel of businessmen who formed a monopoly to control the export of coal from the River Tyne in North East England. They were so known from the medieval practice of "hosting", whereby local businessmen provided visiting merchants with accommodation and introduced them to local traders. The Hostmen acted as middlemen with whom the coal producers and those who shipped the coal to London and elsewhere were forced to deal.
