The 2024 National League Championship Series was a best-of-seven playoff in Major League Baseball's 2024 postseason. It matched the overall #1 seed Los Angeles Dodgers against the sixth-seeded New York Mets. The Dodgers won the series, four games to two, to become National League (NL) champions and advance to the 2024 World Series. For his performance, Dodgers utilityman Tommy Edman won the NL Championship Series Most Valuable Player Award.

The series began on October 13 and ended on October 20. Fox and FS1 televised the games in the U.S.

The Dodgers went on to defeat the American League champion and the Mets fellow Subway Series rival New York Yankees in the 2024 World Series to win their eighth World Series title in franchise history.

The Los Angeles Dodgers qualified for the postseason as the National League West division winner and the league's top seed. They clinched a playoff berth with a victory over the Marlins on September 19. This was the 12th consecutive season in which the Dodgers made the postseason, which remains the longest active playoff streak in major North American professional sports. The Dodgers clinched the National League West division with a victory over the Padres on September 26, their third consecutive division championship and 11th in the past 12 seasons. In the Division Series, they defeated their intrastate division rival San Diego Padres in five games to advance to the National League Championship Series for the first time since 2021 and the seventh time in 12 years (2013, 2016–2018, 2020–2021, and 2024). Their series win against San Diego in the NLDS was the first time that a higher-seeded team won that round in the NL since the Dodgers and Braves both did in 2020. This was Los Angeles' 16th National League Championship Series appearance, which leads the league.

The New York Mets qualified for the postseason as the sixth seed wild card entrant. They clinched a playoff berth for the second time in the past three seasons on September 30 following a victory against the Atlanta Braves in the first game of a doubleheader. In the Wild Card Series, they defeated the National League Central champion and third-seed Milwaukee Brewers in three games, highlighted by Pete Alonso's go-ahead three-run home run in the ninth inning in the winner-take-all Game 3. In the Division Series, they defeated the National League East champion and second-seed Philadelphia Phillies in four games, highlighted by Francisco Lindor's go-ahead grand slam in Game 4 in the sixth inning. The Mets advanced to the National League Championship Series for the first time since 2015, when they most recently won the pennant. The Mets are 64–37 since Grimace, a character from McDonaldland, threw out the first pitch on June 12, with the media, fans, and even the team using this moment as a rallying cry. This was the Mets' ninth appearance in the NLCS.

This was the third straight year that the sixth-seeded team advanced to the NLCS, with the 2022 Phillies and the 2023 Diamondbacks both accomplishing this feat and also the third straight year a sub 90–win team has made the NLCS. Additionally, with the New York Yankees clinching an ALCS berth the night after the Mets, this is the furthest that both New York teams have gone in the postseason since 2000, when the Yankees beat the Mets in the World Series in five games.

This series marked the fourth postseason meeting between the Dodgers and the Mets. This was a rematch of the 1988 NLCS, which the Dodgers won in seven games en route to a World Series title. The other previous postseason meetings were in the 2006 NLDS and, most recently, the 2015 NLDS, both of which the Mets won. They swept the former series and won the latter in five games. The Dodgers won the 2024 regular season series against the Mets, 4–2.

Los Angeles won the series, 4–2.
