Format
Each of the 12 women's basketball teams in the MAC receive a berth in the conference tournament. Teams are seeded per division by conference record with the following tie-breakers:
 * Two-team tie:
 * 1) Head-to-head competition
 * 2) Division record (ten games)
 * 3) Record vs. #1 team in division proceeding through the #6 team, if necessary
 * 4) Non-division record (six games)
 * 5) Record vs. #1 team in the opposite division proceeding through the #6 team, if necessary
 * 6) Coin flip by the Commissioner
 * Three-team tie:
 * 1) Total won–lost record of games played among the tied teams
 * 2) Division record (ten games)
 * 3) Record vs. #1 team in division proceeding through the #6 team, if necessary
 * 4) Non-division record (six games)
 * 5) Record vs. #1 team in the opposite division proceeding through the #6 team, if necessary
 * 6) Coin flip by the Commissioner

Note: Once a three-team tie has been reduced to two teams, the two-team tiebreakers go in effect. If there are multiple ties, the ties are broken from the top down (e.g. a tie for #3 will be broken before a tie for #5).

The top two seeds in each division receive byes into the Quarterfinals. All rounds were held at Quicken Loans Arena.
