The 1978 Commonwealth Games was held in Edmonton, Alberta, Canada, from 3 to 12 August 1978, two years after the 1976 Summer Olympics was held in Montreal, Quebec. They were boycotted by Nigeria, in protest at New Zealand's sporting contacts with apartheid-era South Africa, as well as by Uganda, in protest at alleged Canadian hostility towards the government of Idi Amin. The Bid Election was held at the 1972 Summer Olympics in Munich.

The Commonwealth Games is a quadrennial international multi-sport event among athletes from the Commonwealth of Nations, which consists mostly, but not exclusively, of territories of the former British Empire. The event was first held in 1930 as the British Empire Games and, with the exception of 1942 and 1946, has successively run every four years since. The event was called the British Empire Games from 1930 to 1950, the British Empire and Commonwealth Games from 1954 to 1966, and British Commonwealth Games from 1970 to 1974. The event removed the word British from its title for the 1978 Games and has maintained its current name ever since.
