Postseason playoffs
A total of sixteen teams were selected to participate in the single-elimination tournament from across the country, with invitations that were revealed on Sunday, November 17, 2019. The field included twelve conference champions who received automatic bids. The field was then filled with at-large selections that were awarded to the highest ranked teams that were not conference champions. First-round seedings were based on the final regular-season edition of the 2020 NAIA Coaches' Poll, with certain minor modifications given based on travel and geographic considerations. Each subsequent round also saw minor modifications based on travel and the geography of the remaining teams.

Quarterfinal pairings were announced by the NAIA on November 23, after the first round results were known.

Semifinal pairings were announced by the NAIA on November 30, soon after completion of the day's quarterfinal games.
