|Address||1 Grosvenor Square, London W1K 4AB|

Macdonald House is a seven-storey building in Grosvenor Square in Mayfair, London that is part of the High Commission of Canada in London. Macdonald House hosts the cultural and consular functions, trade and administrative sections of the High Commission, as well as the High Commissioner's official residence. Previously, Macdonald House was the home of the American Embassy in London.
In 1936 the former (residential) buildings on this site were demolished as part of a redevelopment scheme led by the Duke of Westminster. The current building occupies numbers 1 to 3 on the eastern side of the square.
The American embassy moved into the building in 1938. The current US embassy, also in Grosvenor Square, was completed in 1960. During the Second World War when the Chancery was on one side and U.S. General Dwight D. Eisenhower's headquarters on another, Grosvenor Square became popularly known as "Little America."
In December 2008 the Government of Canada revived plans previous to sell the chancery and purchase a building closer to Canada House in Trafalgar Square. 
In February 2010, the government of Prime Minister Stephen Harper cancelled the sale for the third time.
On December 20, 2010 the Department of Foreign Affairs and International Trade announced that Canada House, the High Commission's diplomatic, public and educational space in London, would close to undergo necessary renovations. It re-opened in 2012.
