The American League of Professional Baseball Clubs, or simply the American League (AL), is one of two leagues that make up Major League Baseball (MLB) in the United States and Canada. It developed from the Western League, a minor league based in the Great Lakes states, which eventually aspired to major league status. It is sometimes called the Junior Circuit because it claimed Major League status for the 1901 season, 25 years after the formation of the National League (the "Senior Circuit").

At the end of every season, the American League champion plays in the World Series against the National League champion; two seasons did not end in playing a World Series (1904, when the National League champion New York Giants refused to play their AL counterpart, and 1994, when a players' strike prevented the Series). Through 2017, American League teams have won 65 of the 113 World Series played since 1903, with 27 of those coming from the New York Yankees alone. The New York Yankees have won 40 American League titles, the most in the league's history, followed by the Philadelphia/Kansas City/Oakland Athletics (15) and the Boston Red Sox (13).
The 2017 American League champions are the Houston Astros.
Originally a minor league known as the Western League, the American League later developed into a major league after the American Association disbanded. In its early history, the Western League struggled until 1894, when Ban Johnson became the president of the league. Johnson led the Western League into major league status and soon became the president of the newly renamed American League. Babe Ruth, noted as one of the most prolific hitters in Major League Baseball history, spent the majority of his career in the American League. The American League has one notable difference versus the National League, in that since 1973 it has had the designated hitter rule. Under the rule, a team may use a batter in its lineup who is not in the field defensively, replacing the pitcher in the batting order, compared to the old rule that made it mandatory for the pitcher to bat.
Until the late 1970s, league umpires working behind home plate wore large, balloon-style chest protectors worn outside the shirt or coat, while their brethren in the National League wore chest protectors inside the shirt or coat. In 1977, new umpires (including Steve Palermo) had to wear the inside chest protector, although those on staff wearing the outside protector could continue to do so. Most umpires made the switch to the inside protector, led by Don Denkinger in 1975 and Jim Evans the next year, although several did not, including Bill Haller, Lou DiMuro, George Maloney, and Jerry Neudecker, who became the last MLB umpire to use the outside protector in 1985.
In 1994, the league, along with the National League, reorganized again, into three divisions (East, West, and Central) and added a third round to the playoffs in the form of the American League Division Series, with the best second-place team advancing to the playoffs as a wild-card team, in addition to the three divisional champions. In 1998, the newly franchised Tampa Bay Devil Rays joined the league, and the Arizona Diamondbacks joined the National League: i.e., each league each added a fifteenth team. An odd number of teams per league meant that at least one team in each league would have to be idle on any given day, or alternatively that odd team out would have had to play an interleague game against its counterpart in the other league. The initial plan was to have three five-team divisions per league with inter league play year-round—possibly as many as 30 interleague games per team each year. For various reasons, it soon seemed more practical to have an even number of teams in both leagues. The Milwaukee Brewers agreed to change leagues, moving from the AL Central to the NL Central. At the same time, the Detroit Tigers were moved from the AL East to the AL Central, making room for the Devil Rays in the East. Following the move of the Houston Astros to the American League in 2013, both leagues now consist of 15 teams.
For the first 96 years, American League teams faced their National League counterparts only in exhibition games or in the World Series. Beginning in 1997, interleague games have been played during the regular season and count in the standings. As part of the agreement instituting interleague play, the designated-hitter rule is used only in games where the American League team is the home team.
There were eight charter teams in 1901, the league's first year as a major league, and the next year the original Milwaukee Brewers moved to St. Louis to become the St. Louis Browns. These franchises constituted the league for 52 seasons, until the Browns moved to Baltimore and took up the name Baltimore Orioles. All eight original franchises remain in the American League, although only four remain in the original cities (Detroit, Chicago, Boston, and Cleveland). The eight original teams and their counterparts in the "Classic Eight" were:
- original Baltimore Orioles (went bankrupt and became defunct after 1902 season, not to be confused with the current Baltimore Orioles, see Milwaukee Brewers), replaced in 1903 by the New York Highlanders (became the New York Yankees in 1913)
- Boston Americans (became the Boston Red Sox in 1908)
- Chicago White Stockings (became the Chicago White Sox in 1904)
- Cleveland Blues (became the Cleveland Indians in 1915)
- Detroit Tigers (name and locale unchanged from 1894 forward)
- original Milwaukee Brewers (became the St. Louis Browns in 1902 and the new Baltimore Orioles in 1954)
- Philadelphia Athletics (became the Kansas City Athletics in 1955 and the Oakland Athletics in 1968)
- original Washington Senators (became the Minnesota Twins in 1961)
