The Edmonton Oilers are a professional ice hockey team based in Edmonton, Alberta, Canada. They are members of the Northwest Division in the Western Conference of the National Hockey League (NHL).

The Oilers were founded on November 1, 1971, with the team playing its first season in 1972 as one of twelve founding franchises of the major professional World Hockey Association (WHA). The club renamed itself the Alberta Oilers, intending to represent the whole province, when the Calgary Broncos (a fellow WHA founding franchise in Alberta) relocated to Cleveland, Ohio. However, the team returned to using the Edmonton Oilers name for the following year. The Oilers subsequently joined the NHL in 1979, as one of four franchises introduced through the NHL merger with the WHA.

After joining the NHL, the Oilers quickly went on to win the Stanley Cup on five occasions: 1984, 1985, 1987, 1988 and 1990. As one of the dominant NHL teams of the 1980s, the Oilers team of this era has been honoured with "dynasty" status by the Hockey Hall of Fame.
