Relations between the French Republic and the Commonwealth of Nations have undergone successive periods of change since the Commonwealth's creation.
The Commonwealth's predecessor, the British Empire, was a notable rival to France's own empire. Even through eras of Entente cordiale, decolonisation, and political integration with the United Kingdom (the leading Commonwealth member) in the European Union, there has been conflict between French and Commonwealth interests, particularly in Africa. The Fashoda syndrome has shaped French attitudes to prevent Commonwealth influence in French-speaking countries, believing their interests to be mutually-exclusive.
Despite these rivalries and dual structures, at times, it has been suggested that France join the Commonwealth. In 1956, during the Suez Crisis, during which France and the United Kingdom's interests in the Middle East aligned, it was proposed by French Prime Minister Guy Mollet that France and the UK create a Franco-British Union, with common citizenship and Queen Elizabeth II as head of state. His British counterpart, Anthony Eden, instead proposed that France join the Commonwealth, with Commonwealth citizenship rights and recognising the Queen as Head of the Commonwealth. However, this was rejected by Mollet.
