The 1962 Commonwealth Prime Ministers' Conference[1] was the 12th Meeting of the Heads of Government of the Commonwealth of Nations.

It was held in the United Kingdom in September 1962,[2] and was hosted by that country's Prime Minister, Harold Macmillan.

This meeting saw the expansion of the Commonwealth to include several newly sovereign countries in Africa and the Caribbean.

The main topic of discussion was the British governments negotiations to join the European Economic Community and concerns by Commonwealth nations of the impact of such a move on trade between Britain and the Commonwealth.
