Revenue stamps of British Guiana refer to the various revenue or fiscal stamps, whether adhesive or directly embossed, which were issued by British Guiana prior to the colony's independence as Guyana in 1966. Between the 1860s and 1890s, the colony issued Inland Revenue and Summary Jurisdiction stamps, while revenue stamps and dual-purpose postage and revenue stamps were issued during the late 19th and 20th centuries. In around the 1890s or 1900s, British Guiana possibly issued stamps for taxes on medicine and matches, but it is unclear if these were actually issued. Guyana continued to issue its own revenue stamps after independence.
