The 1998 National League Division Series (NLDS), the opening round of the 1998 National League playoffs, began on Tuesday, September 29, and ended on Sunday, October 4, with the champions of the three NL divisions—along with a "wild card" team—participating in two best-of-five series. The teams were: (1) Atlanta Braves (Eastern Division champion, 106–56) vs. (4) Chicago Cubs (Wild Card, 90–73): Braves win series, 3–0. (2) Houston Astros (Central Division champion, 102–60) vs. (3) San Diego Padres (Western Division champion, 98–64): Padres win series, 3–1.
The Atlanta Braves and San Diego Padres went on to meet in the NL Championship Series (NLCS). The Padres defeated the Braves four games to two to become the National League champion, and lost to the American League champion New York Yankees in the 1998 World Series.

Matchups
Atlanta Braves vs. Chicago Cubs
Houston Astros vs. San Diego Padres
Atlanta vs. Chicago
Game 1
Turner Field in Atlanta, Georgia
The Braves faced the Chicago Cubs, who made it into the playoffs by beating the San Francisco Giants in a tiebreaker for the Wild Card spot and though the Cubs won the season series 6-3 including a three-game sweep in Wrigley Field without NL MVP Sammy Sosa, and a two-game sweep in Turner Field, the Braves proved that the post season would be different. John Smoltz pitched masterfully and Michael Tucker started the scoring with a two-run home run off Chicago starter Mark Clark. Then an Andruw Jones sacrifice fly with two on made it 3–0. In the bottom of the seventh, Ryan Klesko put the game away with a grand slam into right field off of Matt Karchner after three walks off of Clark (one) and Felix Heredia (two walks). Clark allowed four runs, but two were unearned. The Cubs would score in the eighth off Smoltz on Tyler Houston's lead off home run. This ended Smoltz's night, but John Rocker and Kerry Ligtenberg slammed the door on Game 1.

Game 2
Turner Field in Atlanta, Georgia
Game 2 was a pitchers' duel. Kevin Tapani faced Tom Glavine; the two had previously faced each other in the 1991 World Series. Lance Johnson drove in the lone Chicago run in the top of the sixth on a groundout. However, leaving Tapani in to pitch the ninth ultimately cost the Cubs the game. Javy López hit the game-tying home run and Chipper Jones drove in the winning run in the tenth off Terry Mulholland with an RBI single.

Game 3
Wrigley Field in Chicago, Illinois
Game 3 was another pitchers' duel. Greg Maddux faced Rookie of the Year Kerry Wood, hoping to keep the ship afloat for the Cubs. The Braves scored first in the top of the third when Maddux doubled and later scored on a passed ball with two outs. Wood pitched five innings and that was the only run he would allow. Maddux was masterful, carrying a shutout into the bottom of the eighth. In the top of the eighth, Gerald Williams drove in another run with an RBI single off Rod Beck after Terry Mulholland allowed a single and walk. When Andruw Jones was intentionally walked to load the bases, Eddie Pérez belted a grand slam into left field to put the game and the series away. Maddux was lifted after giving up three straight singles in favor in Ligtenberg. Mickey Morandini's sacrifice fly and Mark Graces RBI single made it 6–2 Braves, but Ligtenberg retired the Cubs in order in the ninth. José Hernández flied to center for the final out of the series as the Braves won their first game at Wrigley Field of the season.

1998 NLDS (3–0): Atlanta Braves over Chicago Cubs
Houston vs. San Diego
Game 1
The Astros entered the playoffs with the league's best offense and red-hot pitcher Randy Johnson, who had gone 10–1 since being traded to the Astros in a mid-season deadline deal, well rested for Game 1. However, Padres ace Kevin Brown was more than up for the challenge as he set an LDS record striking out 16 Astros in eight innings before turning the game over to all-star closer Trevor Hoffman for the save. The Padres only managed two runs, including a home run by slugger Greg Vaughn. Despite Brown's dominant performance, the game was not without its tense moments thanks to a less than perfect ninth inning. Hoffman, who had tied the NL record for saves with 53, did allow an unearned run on two hits thanks to a throwing error by third baseman Ken Caminiti. The error by the former Astro brought Houston to within one run before Hoffman slammed the door ending the game at 2–1. This was the first road postseason victory for the Padres.
