The 1987 National League Championship Series took place between October 6^th and 14^th at Busch Memorial Stadium (Games 1, 2, 6, and 7) and Candlestick Park (Games 3, 4, and 5). It matched the East division champion St. Louis Cardinals (95–67) against the West division champion San Francisco Giants (90–72), with the Cardinals winning in seven games. The Cardinals would go on to lose the 1987 World Series to the Minnesota Twins, also in seven games.

San Francisco's Jeffrey Leonard was named the Series MVP despite the fact that his Giants lost the series. Oddly enough, this was the second consecutive year that the NLCS MVP came from the losing team, as Mike Scott had won the award with the Houston Astros the previous year. However, to date, Leonard is the last MVP of any postseason series (League Championship Series or World Series) to have played for the losing team. There is no MVP awarded for the wildcard round or division series
