The 1984 World Series began on October 9 and ended on October 14, 1984. The American League champion Detroit Tigers played against the National League champion San Diego Padres, with the Tigers winning the series four games to one.

This was the first World Series that Peter Ueberroth presided over as commissioner. Ueberroth began his tenure on October 1, succeeding Bowie Kuhn. Ueberroth had been elected as Kuhn's successor prior to the 1984 season, but did not take over until the postseason as he was serving as the chairman of the 1984 Summer Olympics, which ran from July 28 through August 12.

The San Diego Padres won the National League West division by twelve games over both the Atlanta Braves and the Houston Astros, then defeated the Chicago Cubs, three games to two, in the National League Championship Series. The Detroit Tigers won the American League East division by fifteen games over the Toronto Blue Jays, then swept the Kansas City Royals, three games to none, in the American League Championship Series.

The 1984 World Series was a rematch between managers Sparky Anderson (Detroit) and Dick Williams (San Diego). The two had previously faced off in the 1972 World Series, with Anderson managing the Cincinnati Reds and Williams helming the victorious Oakland Athletics. The 1984 Series was Anderson's fifth overall as a manager—in addition to the 1972 Fall Classic, he had also managed the Reds during the 1970 World Series (which they lost to the Baltimore Orioles) and served as skipper during Cincinnati's back-to-back world championships in 1975 and 1976. Anderson's counterpart, Williams, was managing in his fourth World Series; he had headed the Boston Red Sox during the 1967 "Impossible Dream" season, when they won their first pennant in 21 years in a tight race over the Tigers, Minnesota Twins, and Chicago White Sox. After his Athletics won the 1972 World Series, Williams again led them to victory in the 1973 Series over the New York Mets.
