The 1998 National League Championship Series (NLCS), to determine the champion of Major League Baseball's National League, was played from October 7 to 14 between the East Division champion Atlanta Braves and the West Division champion San Diego Padres. It was the seventh-consecutive NLCS appearance for the Braves and they would be heavily favored against the Padres, though their edge in the season series between the two teams was modest, having won 5 of 9. The Padres would go on to the lose in a sweep to the New York Yankees in the World Series in four games.
