Major League Baseball (MLB) is the highest level of play in North American professional baseball and is the organization that operates the National League and the American League. In 2000, the two leagues were officially disbanded as separate legal entities, and all of their rights and functions were consolidated in the commissioner's office. Since that time, MLB has operated as a single league. Composed of 30 teams, MLB is one of the four major professional sports leagues in the United States and Canada.

Each team in the league has a manager who is responsible for team strategy and leadership on and off the field. Assisted by various coaches, the manager sets the line-up and starting pitcher before each game and makes substitutions throughout the game. In early baseball history, it was not uncommon for players to fill multiple roles as player-managers; specifically, they managed the team while still being signed to play for the club. The last player-manager in Major League Baseball was Pete Rose, who began managing the Cincinnati Reds in 1984.

As of the end of the 2023 MLB regular season, the longest-tenured active manager with the same team in Major League Baseball is Kevin Cash, who has led the Tampa Bay Rays of the American League since 2015. The longest-tenured active manager with the same team in the National League is Craig Counsell, who led the Milwaukee Brewers since 2015 until he signed with the Chicago Cubs following the 2023 postseason. The New York Mets, San Francisco Giants, Chicago Cubs, Cleveland Guardians and the Los Angeles Angels will begin the 2024 season with new managers.

Connie Mack holds the Major League Baseball record for most games won as a manager, with 3,731, and most managed with 7,755. The all-time leaders in championships won in the World Series era (1903–present) are Joe McCarthy and Casey Stengel, who each won seven championships with the New York Yankees.

The Atlanta Braves National League franchise originated in Boston, Massachusetts in 1871. The team has employed 45 managers, who have led the team in three different cities: Boston (1871–1952), Milwaukee, Wisconsin (1953–1965), and Atlanta (1966–present). The first manager was Harry Wright. The longest-tenured manager is Bobby Cox, who retired at the end of the 2010 season. Cox served as skipper of the Braves for 21 consecutive seasons (1990–2010), and holds the major league record for managerial ejections, with 151. Cox' win–loss record was 2,058–1,638 with the Braves (he previously managed the Toronto Blue Jays). He won four Manager of the Year Awards (1985, 1991, 2004–2005) and led the Braves to 14 consecutive division titles (3 in the National League West and 11 in the East; 1991–2005 excluding the 1994 strike-shortened season), winning one World Series in 1995. Fredi González succeeded Cox as manager. Gonzalez was fired on May 17, 2016. On May 17, 2016, the Atlanta Braves named Brian Snitker as their interim manager and the 47th manager in club history. He was named permanent manager on October 11, 2016.

The Marlins franchise entered the National League in 1993 as an expansion team and was known as the Florida Marlins until 2011. The franchise's first manager was Rene Lachemann, who accumulated 285 losses during his four-season tenure. Jim Leyland and Jack McKeon each guided the team to World Series victories, in 1997 and 2003, respectively; however, the team has never won a division title. Marlins managers have never lost a playoff series, and Miami is the only franchise in Major League Baseball to accomplish the feat. McKeon is the franchise leader in wins (281). Joe Girardi won the Manager of the Year Award in his only season managing the Marlins (2006). He is the only manager to win the award while fielding a team with a losing record, and he's the only manager to win with a team that finished in fourth place in its division. Jack McKeon was named the team's interim manager in 2011, having been named to the position following the mid-season resignation of Edwin Rodríguez. At the conclusion of the 2011 season, the Marlins hired Ozzie Guillén to be their manager for the 2012 season; however, he was fired following his first season. The Marlins then named Mike Redmond as their manager. Redmond was subsequently fired on May 17, 2015, and replaced by Dan Jennings on an interim basis. After the 2015 season, Don Mattingly signed a four-year contract to become the club's 15th manager. On September 25, 2022, Mattingly stated that he and the Marlins mutually agreed that he would finish the season as manager, and not return to the role in 2023. On October 25, 2022, Skip Schumaker was hired as team's manager. Schumaker resigned after the 2024 season.

The successor to two previous National League franchises in New York City (the Giants and the Dodgers), the New York Mets have existed since 1962 and have played in Queens since 1964, when they vacated the Polo Grounds in Manhattan and moved to Shea Stadium. Casey Stengel was the first of twenty managers. Gil Hodges led the team to their first championship in the 1969 World Series. Davey Johnson is the franchise leader in regular-season wins, with 595 during his seven-season tenure, and he led the Mets to their most recent title in the memorable 1986 World Series. Bobby Valentine managed the team during their next deep playoff run to the 2000 World Series. Terry Collins holds the record for most games managed at 1134, and his Mets record was 551–583. Combined with his managerial tenures with the Houston Astros and Anaheim Angels, his record was 995–1017. The Mets made the playoffs in Collins' fifth season as manager, and played in the 2015 World Series. Terry Collins retired after the 2017 season and was replaced by former Indians Pitching Coach Mickey Callaway who became the club's 21st manager. After two lackluster seasons Callaway was fired on October 3, 2019. On November 1, 2019, the Mets hired their former All-Star center fielder Carlos Beltrán to be their 22nd manager. After Beltran was implicated in the Houston Astros sign stealing scandal, he and the Mets agreed to a mutual parting of ways. On January 22, 2020, the Mets hired quality control coach Luis Rojas as the team's next manager. After 2021 season, the Mets announced that they would not pick up the 2022 option for Rojas. On December 20, 2021, Buck Showalter was announced as the club's 24th manager. Showalter announced that he won't return to the Mets for 2024 season. Carlos Mendoza was named as manager on November 13, 2023.

The National League franchise in Philadelphia was established in 1883 following the dissolution of Worcester. The team adopted the Philadelphia Phillies name in 1884 and has used the moniker since that time. The team's first manager was Bob Ferguson. Charlie Manuel was the manager from 2005 to 2013 until he was fired on August 16, 2013. Manuel was the first Phillies manager since Dallas Green in 1980 to win a World Series (2008) and the first to lead his team to at least three consecutive playoff appearances since Danny Ozark (1976–1978). Manuel's career managerial record is 867–678, having previously managed the Cleveland Indians; his record with the Phillies was 780–636 surpassing Gene Mauch's previous regular season record of 645 wins (1960–68). The Phillies won five consecutive division championships (2007–2011) and back-to-back National League pennants (2008–2009) during Manuel's tenure. Manuel has the most postseason wins (27) in team history, while Ozark has the most playoff losses (9). Larry Bowa is the only Phillies skipper to capture the Manager of the Year Award, which he won in 2001. Four Phillies managers have been inducted into the Philadelphia Baseball Wall of Fame for service to the Phillies: Paul Owens, Bowa, Gavvy Cravath, and Green. Following Charlie Manual's firing in 2013, 3rd base coach Ryne Sandberg was promoted to manager. Sandberg resigned on June 26, 2015, and Pete Mackanin was the hired as a replacement. On September 29, 2017, the club announced that Mackanin would not return as manager. The following day, the Phillies hired Gabe Kapler to be their 54th manager. After two unsuccessful seasons with the club, Kapler was fired. On October 24, 2019, the Philadelphia Phillies hired Joe Girardi as their 55th manager, replacing Kapler. Girardi was fired after a disappointing start to the 2022 season and was replaced by bench coach Rob Thomson.

The Washington Nationals franchise was established in Montreal, Quebec in 1969 as an expansion team. Originally known as the Montreal Expos, the team's first manager was Gene Mauch, who led the team for seven seasons. Felipe Alou is the manager with the most wins (691) and losses (717) in franchise history. He won the 1994 Manager of the Year Award with the club. Jim Fanning was the only Expos club manager to appear in the Major League Baseball postseason; his .529 regular season winning percentage was the highest in franchise history. The only other Expos manager with a winning percentage above .500 is Buck Rodgers (.510), who won the 1987 Manager of the Year Award. After the team relocated to Washington, D.C. in 2004, Dusty Baker was hired as the manager on November 3, 2015, and fired on October 20, 2017. On October 29, 2017, the Nationals named Dave Martinez as their 31st manager. Martinez led the team through their longest ever playoff win through their first World Series in 2019.

The Chicago Cubs franchise began as the Chicago White Stockings in 1876, with Albert Spalding as the franchise's inaugural manager. The team's second manager, Cap Anson, set team records in games managed (2,194), seasons managed (18), and wins (1,242). Frank Chance, part of the famous Tinker to Evers to Chance double-play combination—all of whom managed the franchise at some point—has the best winning percentage in club history (.664) and led the Cubs franchise to World Series victories in 1907 and 1908. During the early 1960s, owner Philip K. Wrigley utilized a "College of Coaches", using a rotating system of multiple managers rather than a single field leader. Lou Piniella managed the Cubs from 2007 to 2010 and led the team to consecutive postseason appearances in 2007 and 2008, becoming the first manager to lead the team to multiple postseasons since Charlie Grimm's four appearances from 1932 to 1935.

On November 6, 2023, the Cubs made a surprising move to fire Ross, and hire former Brewers manager Craig Counsell as the team's 62nd manager.

Similar to their division counterparts, the Cincinnati Reds were established as the Cincinnati Red Stockings in 1882, and have employed 59 managers under 3 different team names since that time. The team's first manager was Pop Snyder, who led the team to an American Association championship in their inaugural season. His .648 winning percentage is highest among Reds managers who have led the team for more than one complete season. Seven managers have led the franchise to the postseason, while four have won World Series: Pat Moran in 1919; Bill McKechnie in 1940; Sparky Anderson in 1975 and 1976; and Lou Piniella in 1990. Anderson is the franchise's all-time leader in regular-season games managed (1,450) and regular-season games won (863).

Established in 1969 as the Pilots in Seattle, Washington, the team moved to Milwaukee, Wisconsin the following season, which brought top-flight baseball back to Wisconsin for the first time since the Braves departed after the 1965 season. The Brewers have been members of the National League since 1998; prior to that, the team played as a member of the American League Central Division. As such, they are one of only two teams, along with the Houston Astros, to appear in the Major League Baseball postseason representing both major leagues. Buck Rodgers and Harvey Kuenn led the team to one American League playoff appearance each, and Dale Sveum led the team to the 2008 National League wild card after replacing the fired Ned Yost with 12 games remaining in the season. Kuenn is the only manager inducted into the Milwaukee Brewers Walk of Fame. Ron Roenicke was hired on November November 2, 2010. Ron Roenicke was fired on May 3, 2015. The Brewers hire Craig Counsell as the team's new manager. and the franchise's all-time managerial playoff wins leader (7).

The Pittsburgh Pirates joined the National League in 1887 after five seasons as members of the American Association. Al Pratt was the first manager in franchise history, while the first manager after joining Major League Baseball was Horace B. Phillips. Fred Clarke, who managed from 1900 through 1915, holds franchise records in wins and losses (1422–969), as well as winning percentage among managers who led the team for a full season or more (.595). Clarke was the first manager to lead the team to the postseason and to win a World Series; other managers to do so include Bill McKechnie (one playoff appearance, one World Series victory), Chuck Tanner (one playoff appearance, one World Series victory), and Danny Murtaugh, who leads franchise managers with two World Series victories and five playoff appearances. Hired prior to the 2011 season, Clint Hurdle was the club's 46th manager since joining the National League in 1887. He was replaced in 2019 by Derek Shelton who was named the 47th manager in team history.

Since their 1882 establishment, the St. Louis Cardinals, originally known as the St. Louis Browns, have employed 64 managers. Ned Cuthbert was the franchise's original manager. Tony La Russa leads the team in regular-season and postseason wins (1,231 and 33), regular-season and postseason losses (1,029 and 25), and playoff appearances (7). La Russa and Hall of Famer Billy Southworth both won two World Series, which is tied for the most in club history by a single manager. Charles Comiskey leads the team in winning percentage (.685) and is one of thirteen Cardinals managers who have been elected to the Baseball Hall of Fame—three of whom (Comiskey, Southworth, Red Schoendienst) had multiple tenures with the club. La Russa and Whitey Herzog each won a Manager of the Year award with the Cardinals (Herzog in 1985 and La Russa in 2002, the fourth of his career). On July 14, 2018, Mike Matheny was fired by the cardinals. Mike Shildt was hired as the club's 64th manager on an interim basis. On August 28, 2018, he was named the permanent manager.

Nine managers have led the Arizona Diamondbacks since their entry into the National League as an expansion team in 1998. Buck Showalter was the team's inaugural manager, winning 250 games in three seasons. Bob Brenly, the franchise leader in regular-season wins (303) and postseason wins (11), is the only manager to win a World Series with the club, in only its fourth season of existence. During the 2004 season, Brenly was replaced by his third-base coach, Al Pedrique, who won 22 out of his 83 games managed. Wally Backman was hired as the Diamondbacks 4th manager on November 1, 2004, but was fired four days later on November 5, 2004, due to off-field issues. Because he didn't coach any games, Backman isn't considered to have been a manager. Bob Melvin took over beginning in 2005, amassing a .500 winning percentage in his 486 games managed. Kirk Gibson was promoted from bench coach to take over as manager after A. J. Hinch's dismissal in July 2010, and remained as manager before being fired with three games left in the 2014 season. After firing Gibson, bench coach Alan Trammell managed the club for the remaining three games, despite also being fired.

He led the team for five seasons, accruing a record of 440–469. Jim Leyland followed Baylor, managing the Rockies for one season and amassing a 70–92 record, after which he was replaced by Buddy Bell. Bell led the Rockies for parts of three seasons until he was replaced during the 2002 season by Clint Hurdle, the team's 4th manager. Hurdle, who managed the team from 2002 until his firing during the 2009 season, leads the franchise in managerial regular-season wins (535) and losses (625), as well as playoff wins (7) and losses (4). Jim Tracy, who was Hurdle's bench coach, replaced him on May 29, 2009.

Hall of Famers to lead the franchise include Alston, Durocher, Lasorda, Casey Stengel, John Montgomery Ward, Wilbert Robinson, Ned Hanlon, Max Carey, and Burleigh Grimes; the last three were inducted primarily as players rather than managers. Following the 2015 season, Dave Roberts was named the club's 32nd manager.

The San Diego Padres joined Major League Baseball as an expansion team in 1969. Preston Gómez managed the team from the inaugural season until 1972. In total, the franchise has had 19 managers.

The Baltimore Orioles franchise was established in 1901 in Milwaukee, Wisconsin as the Brewers (not to be confused with the National League team), with Hugh Duffy as its inaugural manager. The following season, the team moved to St. Louis, Missouri, adopted the St. Louis Browns name, and changed managers to Jimmy McAleer. For the 1954 season, the Browns moved to Baltimore, Maryland, where they became the Orioles, named after Maryland's state bird, and named Jimmie Dykes their new manager. In total, the franchise will have employed 43 managers since its inception upon the hiring of its new manager. Earl Weaver leads Orioles managers in regular-season wins (1,480) and losses (1,060), playoff wins (28) and losses (18), and American League pennants (4). Weaver was the second of three managers to lead the Orioles to a World Series championship, preceded by Hank Bauer and followed by Joe Altobelli. Luman Harris is the franchise leader in winning percentage among managers who have led the team for more than one full season. Members of the National Baseball Hall of Fame and Museum to manage the club include Duffy, Weaver, Bobby Wallace, Branch Rickey, George Sisler, Rogers Hornsby, Jim Bottomley, and Frank Robinson, though Weaver is the only one to have been inducted to the Hall for his accomplishments as a manager. Juan Samuel was the Orioles' interim manager, having replaced Dave Trembley, but was replaced by Buck Showalter as the club's 42nd manager in August 2010. Showalter was fired on October 3, 2018. On December 14, 2018, the Baltimore Orioles named Brandon Hyde their 43rd manager.

The Boston Red Sox of Boston, Massachusetts, began play in 1901 as the Americans and adopted the Red Sox name in 1908. Jimmy Collins was the team's first manager; following the departure of Bobby Valentine at the end of the 2012 season, former Boston pitching coach John Farrell became manager. Joe Cronin, a Hall of Famer elected as a player, holds franchise records for the most regular-season managerial wins and losses (1,071–916), while the team's most successful postseason manager is Terry Francona, (28–14 in 42 playoff games managed). Francona and Bill Carrigan each led the team to two World Series championships; other managers to win championships with the team include Collins, who won the first World Series in 1903, Jake Stahl, and Ed Barrow, whose 1918 championship was the team's last until Francona's 2004 win, which is sometimes attributed to the Curse of the Bambino. Stahl is the franchise's leader in winning percentage among managers (.621). Besides Cronin, other Hall of Fame managers to lead the Red Sox include Collins, Bucky Harris, Joe McCarthy, Lou Boudreau, Billy Herman, and Dick Williams; Boudreau and Herman were inducted to the Hall of Fame as players. Farrell was fired after the loss in 2017 ALDS and was replaced by Alex Cora who became the club's 47th manager. Cora was fired on January 14, 2020, after a sign-stealing scandal. Ron Roenicke was hired as the club's 48th manager on an interim basis on February 11, 2020. On November 6, 2020, Cora was brought back to manage the Red Sox in 2021.

The franchise currently known as the New York Yankees was originally established in 1901 as the Baltimore Orioles (unrelated to their current divisional rivals). After moving to New York City in 1903 and adopting the name New York Highlanders, the team was renamed the Yankees in 1913. Since the beginning of the 1901 season, 35 managers have led the Yankees, beginning with John McGraw, who managed the team until the middle of the 1902 season, when he was replaced. Joe McCarthy, who also managed the rival Red Sox, accumulated the most managerial wins (1,460) and losses (867) as a Yankee skipper during his tenure encompassing parts of 16 seasons. While leading the Yankees, McCarthy won 29 playoff games, the franchise's third-highest total, and 7 World Series championships, tied for the most in team history with Casey Stengel. Joe Torre, who led the Yankees for 12 seasons, has the most postseason wins (76) and losses (47) in team history; he won four World Series during his tenure. McGraw, McCarthy, Stengel and Torre are all members of the Hall of Fame, as are Yankee managers Wilbert Robinson, Clark Griffith, Frank Chance, Miller Huggins (who won three World Series championships with the Yankees), Bill Dickey, Yogi Berra, and Bob Lemon; Chance, Dickey, Berra, and Lemon were inducted as players rather than as managers. Also notable among Yankee managers is Billy Martin, who was named the Yankees skipper for five different tenures, leading the team from 1975 to 1978, and during the 1979, 1983, 1985, and 1988 seasons.

The Minnesota franchise began its life as the Washington Senators in Washington, D. C., where they played from their inception in 1901 to 1960. In the early 20th century, the Senators were managed consecutively by three future members of the Baseball Hall of Fame, bookended by Bucky Harris, who managed the team from 1924 to 1928 and again from 1935 to 1942.

While the Oakland Athletics have played under the same name since their establishment in 1901, the team has played in three different locations. The franchise was initially based in Philadelphia, Pennsylvania and was managed by Connie Mack, a member of the Baseball Hall of Fame and often called one of the best managers in history.
