Qualification
A total of 64 bids are available for each tournament: 24 automatic bids (awarded to the champions of the twenty-two Division II conferences) and 40 at-large bids.

The sixty-four bids are allocated evenly among the eight NCAA-designated regions (Atlantic, Central, East, Midwest, South, South Central, Southeast, and West), each of which contains three of the twenty-four Division II conferences that sponsor men's basketball. Each region consists of three automatic qualifiers (the teams who won their respective conference tournaments) and five at-large bids (which are awarded regardless of conference affiliation).

Six teams qualified for their first NCAA Division II tournament in 2018: Lees–McRae, Ohio Dominican, Point Loma Nazarene, Saint Martin's, Southern Nazarene, and West Florida.
