The Franc Poincaré is a unit of account that was used in the international regulation of liability. It is defined as 65.5 milligrams of gold of millesimal fineness .900. Formerly it was identical to the French franc, although it has not been so since the 1920s.

Practice on its conversion to national currencies varies from state to state; in most states the conversion factor is based not on the market price of gold, but on an official price (a remnant of the gold standard, frequently far below its market price today).
