The All-Atlantic Hockey Teams are composed of players at all positions from teams that are members of the Atlantic Hockey Association, an NCAA Division I hockey-only conference.
Each year, at the conclusion of the Atlantic Hockey regular season, the head coaches of each member team vote for players to be placed on each all-conference team.
The all-conference teams are composed of one goaltender, two defencemen and three forwards.
Should a tie occur for the final selection at any position, both players will be included as part of the superior team with no reduction in the number of players appearing on any succeeding teams (as happened in 2004–05 and 2008–09).
Due to the conference playing in two separate pods (East and West) for the 2020–21 season, as a result of the COVID-19 pandemic, Atlantic Hockey named two all-conference and an all-Rookie team for each pod.
