A joint issue is the release of stamps or postal stationery by two or more countries to commemorate the same topic, event or person. Joint issues typically have the same first day of issue and their design is often similar or identical, except for the identification of country and value.

Continental joint issues Europa postage stamps : Between 1956 and 1973 the postal authorities of several European nations issued stamps with a common design but since 1974 a common topic is used on stamps issued each year. These are not true joint issues, because they do not share the same designs or dates of issue.

An early unrealized trans-Atlantic joint issue 1914 peace commemoratives: In 1914, the United Kingdom, the Dominion of Canada and the United States agreed on a plan by which each of the three nations would issue its own series of stamps that year to commemorate the 100 years of Anglo-American peace that had prevailed since the end of the War of 1812. After the outbreak of World War I later that year, however, the UK and Canada deemed it inappropriate to issue peace stamps and withdrew from the project. The US had already produced essays for 2¢ and 5¢ stamps but canceled further plans for the designs. (This would not have been a true joint issue because each country would have designed its stamps individually.)

Australia The Australia Post has collaborated several times with the postal administration of another country to release a joint issue.
