The American Association of Independent Professional Baseball is an independent professional baseball league founded in 2005. It operates in the central United States and Canada, mostly in cities not served by MLB teams or their minor league affiliates. Miles Wolff is the league commissioner. League offices are located in Durham, North Carolina. Though a separate entity, the league shares a commissioner and director of umpires with the Canadian American Association of Professional Baseball.
The American Association was founded in October 2005 when the St. Paul Saints, Lincoln Saltdogs, Sioux City Explorers, and Sioux Falls Canaries announced they were leaving the Northern League. Around the same time, the Central Baseball League announced it was disbanding after four seasons. The Fort Worth Cats, Shreveport-Bossier Sports, Pensacola Pelicans, Coastal Bend Aviators, and El Paso Diablos joined the four former Northern League teams and the expansion St. Joe Blacksnakes to form the American Association as a ten-team league. The new league began play in 2006, with a 96-game schedule, which has since expanded to 100 games.
2008 saw the league lose the Blacksnakes and Aviators, with the Grand Prairie AirHogs and Wichita Wingnuts joining in their place. In 2011 and 2012 the league went through a significant shift. Fort Worth left the league to join United League Baseball, while Shreveport and Pensacola both relocated. The Pelicans moved to Amarillo, Texas and became the Amarillo Sox (later the Amarillo Thunderheads) while Shreveport, who had changed their name to the Shreveport-Bossier Captains, moved to Laredo, Texas and became the Laredo Lemurs. In addition, four more Northern League franchises ( Fargo-Moorhead RedHawks, Gary SouthShore RailCats, Kansas City T-Bones, and Winnipeg Goldeyes) joined the American Association as that league's stability came into question.
For the 2012 season, the American Association began interleague play with the Can-Am League.  The two leagues are both headquartered in Durham, North Carolina, and both have Miles Wolff as their commissioner. This was similar to interleague play in Major League Baseball, but American Association and Can-Am League are separate legal entities and have separate playoffs/championships.
At the end of the 2013 season, due to the Tucson Padres relocating to their city, the El Paso Diablos suspended operations. The team was eventually revived and relocated, operating as the Joplin Blasters. The Blasters ceased operations after the conclusion of the 2016 season.
On November 19, 2015, Miles Wolff announced that there would no longer be interleague play. It also was announced that for the Amarillo Thunderheads and Grand Prairie AirHogs would operate as a joint team ( Texas AirHogs) playing 25 games in Amarillo and 25 games in Grand Prairie to make up a 12-team league.   The team remained in Grand Prairie full-time in 2017, with the Cleburne Railroaders joining league the same season. Shortly before the 2017 season, the Laredo Lemurs withdrew from the league.  They were temporarily replaced by the Salina Stockade from the Pecos League for the season. The Chicago Dogs joined for 2018. 
Typically the American Association recruits college, ex-major and ex-minor players. Former affiliated-league players that get injured or have other circumstances join the AA as an opportunity to get re-signed by major league organizations. Other players consist of college players who were not drafted into MiLB, but seek the opportunity to be seen by major league scouts and possibly get signed by major league organizations. Other former MLB players join the AA as a way to stay involved in baseball after their career as a major league player, often as coaches and managers.
As of 2008, the salary cap for each team was $100,000, with a minimum salary of $800 per month.  The price of an expansion team is also about $750,000.  This is in stark contrast with the minor and major leagues. Commissioner Miles Wolff stated in an interview that "We have to pay the salaries of the players, which they don't in an affiliated [league]. It's a much riskier business. Just because of the longevity and tradition, we usually don't get the best cities, either, so some of the markets we're in are not great markets. But as I say, I think it's a better product."
