Philadelphia won the series, 3–2.

The 1980 NLCS featured Joe Morgan on the Astros and Pete Rose on the Phillies, the leadoff and 2-hole hitters in the Big Red Machine batting line-up, who dominated baseball for much of the 1970s.

Game 1 was the most ordinary contest of the series. Starters Ken Forsch and Steve Carlton dueled for the first five innings, with only one run scored by Houston in the third on an RBI single by Gary Woods. Philadelphia's Greg Luzinski essentially decided the game in the sixth when he homered after Pete Rose had singled. This was the only home run of the entire series. The Phillies added another run in the seventh on a run-scoring single by pinch-hitter Greg Gross. Tug McGraw relieved Carlton at the start of the eighth and allowed only a walk during the last two innings for the save. Despite pitching fairly well in a complete game effort, Forsch took the loss.

The Astros arrived in Philadelphia only hours before the first pitch after defeating the Los Angeles Dodgers at Dodger Stadium in a one-game playoff the previous afternoon to win the Western Division championship.

This was the first home postseason win for the Phillies since the Game 1 of the 1915 World Series, ending a ten-game home postseason losing streak.

Houston evened the series in Game 2, a seesaw contest that would prove typical of the series as a whole. Houston opened the scoring in the third when Terry Puhl singled home Craig Reynolds after a sacrifice bunt by Nolan Ryan. The Phillies took the lead with two runs in the fourth on RBIs from Greg Luzinski and Garry Maddox. Houston evened the score in the seventh when Ryan walked and was doubled home by Puhl, and went ahead in the eighth after Joe Morgan doubled and scored on a single by José Cruz.

After loading the bases in the seventh but failing to score, the Phillies got a run in the eighth to tie the game 3–3 when Maddox singled home pinch-runner Lonnie Smith. The Astros went 1–2–3 in the ninth but the Phillies loaded the bases with one out in their half of the inning on singles by Bake McBride, Mike Schmidt and Smith. But Manny Trillo, who would eventually win the series MVP award, struck out and Maddox fouled out to end the threat.

The tenth inning turned disastrous for the Phillies as Houston used three hits to score four runs, with an RBI single by Cruz (complete with an error that moved him to second base), a run-scoring groundout by César Cedeño, and a two-run triple by Dave Bergman. The Phillies got an unearned run in the bottom of the inning on an error by Reynolds at shortstop. Astros reliever Joaquín Andújar came in to the game to try and stop the bleeding, which included two on with two out and Mike Schmidt at the plate. On a count of 3-0, Schmidt lined a pitch harmlessly into right field into the glove of the fielder to end the game and tie the series at 1–1.

Houston's Astrodome was always known as a pitcher's park, and the domed stadium lived up to its reputation when the series moved there for Game 3. The two teams' pitching staffs combined to yield only 13 hits and one run in the game's 11 innings. Houston's Joe Niekro pitched ten strong innings but missed out on what would have been a win, while Phillies closer Tug McGraw took the loss. Both teams did get men to third on a few occasions: Houston in the first and fourth and Philadelphia in the third. But the staffs held firm until the bottom of the 11th. Joe Morgan led off the inning for the Astros with a triple to right. After two intentional walks Denny Walling hit a sacrifice fly to bring home the game's only run and give Houston the victory. The Astros were now just one win away from the franchise's first appearance in the World Series.

In what was by now a familiar pattern, Game 4 turned into a back-and-forth contest that wasn't decided until extra innings.

The fourth inning of this game was especially eventful. In the top, Bake McBride and Manny Trillo opened with back-to-back singles off Vern Ruhle. Garry Maddox then hit a low liner back to the mound that Ruhle reached down and appeared to catch (replays were inconclusive). Plate umpire Doug Harvey at first made no call on the play due to his view being blocked by Maddox. Ruhle threw to first baseman Art Howe to either double off Trillo or retire Maddox (according to the call) and Harvey asked for a ruling from first-base umpire Bob Engel. Engel ruled a catch, meaning Maddox was out and Trillo was doubled off. Howe, seeing McBride at third base, then ran down and touched second for an apparent triple play and the Astros left the field as the inning was apparently over. Phillies manager Dallas Green and the Phillie infielders (especially Pete Rose) heatedly protested that Ruhle trapped the ball, but the call was not changed. Harvey allowed McBride to return to second, determining that his original hesitation and conferring with Engel caused McBride to run to third. Astros manager Bill Virdon protested the decision to declare only two outs and McBride on second, but to no avail. The umpires then consulted with National League President Chub Feeney, who was seated in the first row behind home plate, and Feeney agreed with the ruling. Green and the Phillies then resumed their heated disagreement, and both the Phillies and the Astros decided to play the game under protest. After a total of 20 minutes' worth of arguing from both sides, Larry Bowa grounded out for the third out of the inning. Neither teams' protest was upheld by Feeney.

The bottom of the fourth featured two fielding gaffes by Phillie left-fielder Lonnie Smith as the Astros got their first run. Enos Cabell doubled to left on what appeared to be a catchable fly ball. Smith mistakenly turned to face the left field wall as if the ball would carom, but the ball instead dropped on the warning track a few feet away from him. After Joe Morgan grounded Cabell to third, Gary Woods walked. Howe then hit a fly ball to left that Smith caught as both runners tagged. As Smith attempted to throw home to retire Cabell, the ball slipped from his hand and Cabell scored. Woods reached second and attempted to advance to third on the miscue, but Smith recovered the ball and threw him out on a close play as the Astros protested once again.

The Astros got another run in the fifth as Luis Pujols tripled and scored on a single by Rafael Landestoy. In what would prove to be critical failings, the Astros loaded the bases in both the sixth and seventh but couldn't add to their lead. In the sixth, a run for the Astros was taken off the board when Woods left third base too early on a sacrifice fly attempt and the Phillies successfully appealed.

The Phillies took advantage by going ahead with three runs in the eighth. Pinch-hitter Greg Gross and Smith opened the inning with singles off Ruhle and Rose singled in Gross. Smith advanced to third and Rose to second on the throw to third. Mike Schmidt then beat out a grounder up the middle, scoring Smith to tie it and moving Rose to third. After McBride struck out, Trillo hit a sinking line drive that Jeffrey Leonard made a shoestring catch-on and Rose tagged and scored the go-ahead run. However, on yet another "catch/no catch" controversy, Schmidt was doubled off first (ending the inning), thinking Leonard trapped the ball.

The Astros didn't go quietly and leveled the score in the bottom of the ninth on an RBI single by Terry Puhl. But the tenth was ruinous for Houston. With two out and the score tied at 3–3, the Phillies' Greg Luzinski entered as a pinch-hitter and doubled home Rose with the go-ahead run on a close play at the plate, with Rose running over Astros catcher Bruce Bochy. Manny Trillo then singled home Luzinski with an insurance tally. The Astros went 1–2–3 in the bottom of the tenth, and the series was tied. This was Luzinski's second game-winning hit in the Championship Series, coming after a subpar regular season for the slugger.

Game 4 of the series was a Saturday afternoon affair that ran into the early evening of October 11. An NCAA football game between the University of Houston and Texas A&M had been scheduled to begin at 7:00 p.m. Rather than move the game to a different day or to another stadium, the schools elected to play the game at the Astrodome as scheduled. The conversion of the Astrodome from baseball to football took several hours and the football game did not kick off until 11:33 p.m. The game ended at 2:41 a.m. with the Houston Cougars taking a 17–13 victory over Texas A&M. The Astrodome crew then began work on converting the Dome back to a baseball setup for Game 5 of the NLCS.

Game 5 capped the series in fitting fashion, with seemingly endless surprises and excitement. The Astros jumped to an early lead in the first on a run-scoring double by José Cruz. Philadelphia bounced back to take the lead on a two-run single by Bob Boone in the second. The Astros saw Luis Pujols and Enos Cabell thrown out at the plate in the second and fifth, but finally broke through to tie the game at 2 on an unearned run in the sixth, due to an error by Philadelphia's LF Greg Luzinski.

Houston took what seemed like a solid 5–2 lead in the seventh on an RBI single by Denny Walling, a wild pitch from Phillies reliever Larry Christenson, and a run-scoring triple by Art Howe. A three-run deficit in the eighth inning against Nolan Ryan seemed insurmountable. But the Phillies would not die. They loaded the bases with nobody out on three straight singles, including an infield hit by Bob Boone and a bunt single by Greg Gross. Two runs came in on a walk to Pete Rose and a ground-out by Keith Moreland. An RBI single by Del Unser tied the game at 5, and then series MVP Manny Trillo put the Phillies ahead with a two-run triple.

The Astros promptly came back to tie the game in the bottom of the eighth, with Rafael Landestoy and José Cruz each singling in a run. Neither team scored in the ninth, but the Phillies got doubles from Unser and Garry Maddox in the tenth to take an 8–7 lead. Philadelphia's Dick Ruthven retired the Astros in order in the bottom of the tenth the last out being a soft liner to Maddox, and the Phillies had won their first pennant since 1950. Philadelphia went on to defeat the Kansas City Royals four games to two in the World Series.
