The 1984 National League Championship Series was played between the San Diego Padres and the Chicago Cubs from October 2 to 7. San Diego won the series three games to two to advance to the World Series. The 1984 NLCS was the first postseason series ever for the Padres since the franchise's beginning in 1969, and the first appearance by the Cubs in postseason play since the 1945 World Series. The series took a disastrous turn for Chicago after a promising start, which contributed to the popular mythology of the "Curse of the Billy Goat." The series was also the last best-of-five NLCS. In 1985, the League Championship Series changed to a best-of-seven format.
