2023 Atlantic League season

The 2023 Atlantic League season was the 26th season of the Atlantic League. There was a ten-team 126-game schedule. The Spire City Ghost Hounds were introduced to the league.

The Lancaster Barnstormers defeated the Gastonia Honey Hunters in the championship series, capturing their second consecutive championship and 4th in franchise history.

Rules
In April 2023, it was announced that the Atlantic League would be testing three rules for the 2023 season:


 * The "designated pinch-runner" rule will have clubs designate a pinch runner that is not in the starting line up. That player can be substituted into the game at any point as a baserunner, but unlike typical substitutions the player that is substituted for as well as the pinch-runner will be allowed to return to the game with no penalty.
 * Pitchers will be allowed only one disengagement per at-bat. Any additional disengagements will be counted as a balk unless an out is recorded.
 * The "double-hook" rule will continue being used in its 2022 form.
