Postseason
The 2017 NCAA Division II Football Championship was the 45th edition of the Division II playoffs. The playoffs began on November 18 and concluded with the championship game on December 16.

The field consisted of 28 teams, seven from each of the four super regions. The participants in each region were determined by the regional rankings; if a conference's highest-ranked team was ranked in the top eight, that team qualified via the "earned access" provision, and all other participants were selected directly from the rankings. The top seed in each region received a first-round bye. After the quarterfinals, the regional winners were reseeded one through four, with No. 1 meeting No. 4 in the semifinals and No. 2 meeting No. 3.
