The Triple-A East is a 20-team Minor League Baseball league that began operating in the United States in 2021. Along with the Triple-A West, it is one of two leagues playing at the Triple-A level, which is one grade below Major League Baseball (MLB). The league was created in 2021 in conjunction with MLB's reorganization of the minor leagues. It is made up of the 14 teams formerly of the Triple-A International League, four teams from the Triple-A Pacific Coast League, one from the Double-A Southern League, and one from the independent American Association of Professional Baseball. The Triple-A East has teams in 14 states stretching from Papillion, Nebraska, to Worcester, Massachusetts, and from St. Paul, Minnesota, to Jacksonville, Florida.
Prior to the 2021 season, Major League Baseball assumed control of Minor League Baseball in a move to increase player salaries, modernize facility standards, and reduce travel through better geographical alignment. The two existing Triple-A leagues, the International League and Pacific Coast League, were disbanded and replaced with the Triple-A East and Triple-A West. Twenty teams were organized into the Triple-A East: the 14 teams of the International League, the four easternmost teams from the Pacific Coast League, one promoted from the Double-A Southern League, and one moving from the independent American Association of Professional Baseball.
Initially, the inaugural 2021 season was scheduled to begin on April 6, but Opening Day was postponed until May 4 to temporarily eliminate commercial air travel and give players the opportunity to be vaccinated against COVID-19 before the season began. The original 142-game schedule was shortened to 120 games with all contests before that date being cancelled. Teams will play limited opponents in 2021 due to travel restrictions in place due to the COVID-19 pandemic. Some teams will play only clubs in their own divisions, while others will play division opponents as well as some teams from other divisions.
The league is divided into three divisions: Midwest, Northeast, and Southeast. The Midwest and Southeast Divisions each consist of seven teams, while six teams makeup the Northeast Division. The 2021 season consists of 120 games scheduled per team divided into series of six games each from Tuesday to Sunday with league-wide off days every Monday. The 2021 schedule originally included a three-day All-Star break from July 12-14, but the break was removed after the rescheduling of Opening Day. It does not include a scheduled postseason for championship playoffs or the Triple-A National Championship Game.

The league's first no-hitter occurred on May 9, 2021, the sixth day of its inaugural season, when four Iowa Cubs pitchers combined to no-hit the Indianapolis Indians, 2-0, at Principal Park in Des Moines, Iowa. The feat was accomplished by starting pitcher Shelby Miller, who was making a major league rehab appearance, and relievers Tommy Nance, Brad Wieck, and Ryan Meisinger.
