Most Consecutive ALCS appearances goes to the Houston Astros that holds the record of 7 straight appearances from 2017 to 2023. Following them, the Oakland Athletics made it to the ALCS consecutively for five years.
The Astros have been in the League Championship seven times, winning four AL titles. They were the World Series champions in 2022.
Between 1971 and 1975, the Oakland Athletics consistently reached the ALCS, making them the second-longest team to do so.
Over time, they’ve secured 15 AL titles, making them one of the top teams in the American League.
The New York Yankees, also from the AL, stand out in baseball history. Of all 30 MLB teams, they’ve won an impressive 27 World Series and 40 AL titles since 1901, the year MLB started.
In 1969, MLB decided to divide into four divisions. From then on, each division’s top team competed in the Championship Series for their league. This format stayed, even when more playoff rounds were added in 1995.
Every year, the champions from both leagues go head-to-head in the World Series.
Most ALCS Appearances: Who Tops the List?
The Houston Astros hold the record for making the ALCS appearances consecutively 7 times, spanning the years 2017 to 2023. Notably, the 1994 season is not considered since there were no playoffs that year in MLB.
As of now, the Astros are the sole team with this ongoing streak, which could extend if they continue to succeed in the ALDS in the future.
Following them, the Oakland Athletics made it to the ALCS five times in a row, from 1971 to 1975.

The ALCS began in 1969 when the MLB split into four parts. Before this change, teams with the best seasonal records received the League Pennants.
Houston Astros
From 2017 to 2023, the Houston Astros marked seven consecutive seasons in the ALCS, a record unmatched in current MLB.
Since 2013, they’ve competed in the American League. In the recent six years, the Astros consistently reached the American League playoffs, clinching the World Series title in both 2017 and 2022.
Prior to 2013, they were part of the National League from 1962 to 2012. During that time, they made it to the Championship series just once in their five-decade National League tenure.
Oakland Athletics
The Athletics rank just behind the Astros in terms of ALCS appearances. They made it to the Championship series every year from 1971 to 1975.
In the early seventies, their excellent performances earned them the nickname “Swingin A’s.” This was the time they clinched World Series titles three times in a row, from 1972 to 1974.
Additionally, they reached the championship three years consecutively from 1988 to 1990. In total, the A’s have secured 15 pennants in the AL, considering their history as the Philadelphia Athletics and the Kansas City Athletics.
New York Yankees
The Yankees hold the record for the most ALCS appearances in 18 seasons, leading the American League. Between 1998 and 2001, they participated in four consecutive AL championships.
From 1998 to 2000, the New York Yankees clinched three back-to-back World Series titles. They are among the top MLB teams, boasting 27 World Series victories.
While the Yankees have claimed 40 AL pennants since their initial victory in 1921, they’ve only made it to 18 ALCS matches since the Championship series started in 1969. Before this, they set an impressive record, winning five consecutive AL Pennants multiple times.
After their four-year run concluded in 2001, they’ve achieved ALCS appearances consecutively only twice.
Baltimore Orioles
From 1969 to 1971, the Orioles consistently made it to the ALCS appearances, marking the longest streak in three years.
Within this timeframe, they also clinched their second World Series championship. After this initial three-year run, the Orioles managed to reach the ALCS consecutively only on two occasions: first in 1973-1974 and then in 1996-1997.
Kansas City Royals
The Kansas City Royals made it to the ALCS three times consecutively from 1976 to 1978. However, they only managed to get to the championship twice in a row.
In 1985, the Blue Crew clinched their first World Series title after their success in the ALCS. This was during their back-to-back ALCS appearances in 1984 and 1985.
Toronto Blue Jays
The Blue Jays played in the ALCS for three straight years from 1991 to 1993. During the last two of these years, they won the World Series.
This three-year period was the peak for the Toronto Blue Jays since they started in 1977. They made history as the first Canadian team in MLB to win the World Series in 1992.
Jack Morris, a pitcher, played a big role in these victories. He got the World Series MVP award for playing a full 10-inning game without letting the other team score in the last World Series game.
Detroit Tigers
The Detroit Tigers achieved three straight ALCS appearances from 2011 to 2013. In 2012, during this run, they reached the World Series.
However, they faced defeat against the San Francisco Giants. This was the first time since 1969 that the Tigers participated in consecutive Championship series.
Boston Red Sox
The Boston Red Sox achieved ALCS appearances in two consecutive seasons, 2003 and 2004. They did this again in 2007 and 2008.
In both of these streaks, the Red Sox clinched the World Series title once, in 2004 and again in 2007. To date, the Boston Red Sox have reached the ALCS 11 times and secured 6 pennants.
Most NLCS Appearances: Who Tops the List?
The Atlanta Braves set the record for the most continuous appearances in the NLCS, spanning from 1991 to 1999.
Notably, the 1994 season is not counted because playoffs were not held that year. This eight-season streak by the Braves is the longest in MLB history.
During this period, they clinched five NL Pennants and secured their third World Series championship.
Here’s a list of teams with the highest number of NLCS showings since 1969:
- Atlanta Braves: 8 seasons from 1991 and 1999.
- St. Louis Cardinals: 4 seasons from 2011 to 2014.
- Philadelphia Phillies: 3 seasons from 2008 to 2010.
- Los Angeles Dodgers: 3 seasons from 2016 to 2018.
- Chicago Cubs: 3 seasons from 2015 to 2017.
- Pittsburgh Pirates: 3 seasons from 1990 to 1992.
From 2011 to 2014, the St. Louis Cardinals consistently reached the NLCS for four seasons. During this period, they secured two NL Pennants and clinched the World Series in 2011.
The Phillies have played in the NLCS 10 times since 1969, winning the title six times. Notably, they clinched the title consecutively from 2008 to 2010.
The Los Angeles Dodgers lead in NLCS showings, participating in 15 seasons up to 2023. They’ve secured 24 NL Pennants and are among the top teams in terms of World Series victories.
The Brewers had only two appearances in the NLCS, in 2011 and 2018. Interestingly, they remain the sole National League team that hasn’t won a championship series yet.
