The most successful postseason team in MLB history is the New York Yankees, who have achieved three of the four instances of a franchise winning more than two World Series championships in a row (one streak each of durations 3, 4, and 5 seasons) and five of the six instances of a franchise winning the league pennant (i.e., an appearance in the World Series) more than three times in a row (three streaks of 4 seasons and two streaks of 5 seasons). The only other franchises to achieve these milestones are the Oakland Athletics, who won three consecutive championships from 1972 to 1974, and the New York Giants, who won four consecutive pennants from 1921 to 1924. The Yankees also achieved a remarkable run of appearing in 15 of the 18 World Series from 1947 to 1964.
Beginning in 1969, MLB split into four divisions, and the winners of each competed in the League Championship Series, with the winners advancing to the World Series. When a multi-tier playoff system was implemented in 1995, the LCS remained the series that determined the pennant-winner. The longest streak of consecutive LCS appearances belongs to the Atlanta Braves with 8 in a row from 1991 to 1999 (not counting 1994, when there were no playoffs), while the second-longest belongs to the Oakland Athletics with 5 in a row from 1971 to 1975.
Further expansion of the postseason began in 1995, with eight teams entering the playoffs each year (further expanded to ten teams in 2012). In this era, the Braves entered the postseason 14 consecutive years from 1991 to 2005 (again not counting 1994), while the Yankees had a streak of 13 appearances from 1995 to 2007. However, all other postseason appearance streaks of 5 years or more predate the expanded-postseason era and are mentioned above, except for 5-year runs by the Cleveland Indians (1995–1999), the Philadelphia Phillies (2007–2011), the St. Louis Cardinals (2011–2015), and an ongoing 8-year run by the Los Angeles Dodgers (2013–2020).
World Series championship streaks
The Yankees have achieved one streak each of 3, 4, and 5 championships in a row, and the Athletics have achieved a streak of 3 in a row. Back-to-back championships have been achieved an additional ten times.

League Championship Series appearance streaks
The Braves appeared in every LCS held during the 1990s, which is 8 in a row, but won only 1 championship during that time. The Athletics achieved an LCS appearance streak of 5 in a row, centered on their 3 championships in a row. The Yankees and Cardinals have each achieved an LCS appearance streak of 4 in a row. Three LCS appearances in a row have been achieved an additional thirteen times, and back-to-back LCS appearances an additional twenty-two times.
Three teams (the Orioles, Pirates, and Yankees) achieved multiple LCS appearance streaks in and around the 1970s, each adding up to 5 appearances in 6 years.
The LCS began in 1969. Before that, the two regular season champions were awarded the pennants and went directly to the World Series.

Postseason appearance streaks
The Braves and the Yankees have achieved respective streaks of 14 and 13 consecutive appearances in the postseason, centered on the 1990s and 2000s. The Dodgers have an ongoing streak of 8 consecutive appearances. Five postseason appearances in a row have been achieved an additional six times, four in a row an additional seven times, three in a row an additional twenty-eight times, and back-to-back postseason appearances an additional fifty times.
The Yankees appeared in 17 of the 18 postseasons from 1995 to 2012, and 15 of the 18 postseasons from 1947 to 1964 (see pennant near-streaks above). Five teams (the Indians, Cardinals twice, Red Sox, and Angels) achieved multiple postseason appearance streaks in and around the 1990s and 2000s, each adding up to 6 appearances in 7 or 8 years. The Phillies appeared in 6 of the 8 postseasons from 1976 to 1983.
Postseason appearance streaks have become more common in recent years, as the postseason has been progressively restructured to include more teams (originally two, four since 1969, eight since 1995, ten since 2012).
