The 17th G7 Summit was held in London, England, United Kingdom between July 15 to 17, 1991. The venue for the summit meetings was Lancaster House in London.

The Group of Seven (G7) was an unofficial forum which brought together the heads of the richest industrialized countries: France, Germany, Italy, Japan, the United Kingdom, the United States, Canada (since 1976) and the President of the European Commission (starting officially in 1981). The summits were not meant to be linked formally with wider international institutions; and in fact, a mild rebellion against the stiff formality of other international meetings was a part of the genesis of cooperation between France's President Giscard d'Estaing and West Germany's Chancellor Helmut Schmidt as they conceived the first Group of Six (G6) summit in 1975.

The G7 is an unofficial annual forum for the leaders of Canada, the European Commission, France, Germany, Italy, Japan, the United Kingdom and the United States.

The 17th G7 summit was the first summit for British Prime Minister John Major and the last summit for Italian Prime Minister Giulio Andreotti. It was also the last summit for Japanese Prime Minister Toshiki Kaifu.
