• December 1 – UC Riverside head coach Mike Magpayo became the first head coach of Asian or Filipino descent to coach and won a Division I game in their 57–42 victory over Washington. Magpayo had missed the Highlanders' season opener on November 25 against Pacific due to his child's birth.

• February 21 – Iowa center Luka Garza scored 23 points in a win against Penn State to become the school's all-time leading scorer, breaking a 32-year-old record previously held by Roy Marble (2,116 points).

Ten schools joined a new conference for the 2020–21 season with four schools leaving Division II for Division I.

• James Madison opened the new Atlantic Union Bank Center on November 25, 2020, defeating Division II Limestone 89–55.
• Liberty played its first game at Liberty Arena, winning 78–62 over Saint Francis (PA) on December 3, 2020. The first event at the arena, which had officially opened on November 23, was a women's game on December 1.

Three of the four new D-I members for this season are using existing on-campus facilities:

• Dixie State plays in Burns Arena.
• Tarleton State plays in Wisdom Gym.
• UC San Diego plays in RIMAC Arena.

The other D-I newcomer, Bellarmine, announced a multi-year deal with the Kentucky State Fair Board on November 2, 2020, to play home games at Freedom Hall, located at the Kentucky Exposition Center near Louisville Muhammad Ali International Airport. The arena had been home to Louisville for more than 50 years before that team moved to the downtown KFC Yum! Center in 2010. Due to COVID-19 restrictions, Bellarmine could only seat 300 at its on-campus facility, Knights Hall. With Freedom Hall's basketball capacity of 18,252, the Knights were able to seat 2,700.

• High Point had originally planned to open Nido and Mariana Qubein Arena and Conference Center for the 2020–21 season. However, construction delays brought on by COVID-19 led to the university delaying the new arena's opening until 2021–22, meaning that the Millis Center was in use for one more season.

• This was intended to be Idaho's final season at the Kibbie Dome, a facility also home to Idaho football, with its basketball configuration known as Cowan Spectrum. When Idaho moved its 2020 football season to spring 2021, it displaced the men's and women's basketball teams, forcing them to use Memorial Gymnasium. The latter facility had been home to both basketball teams before the Kibbie Dome opened in 1976, and remained a part-time home for both. The school plans to open the new Idaho Central Credit Union Arena for the 2021–22 season. The Dome will remain in use for football and several other sports.

• Due to COVID-19 restrictions in Santa Clara County, Santa Clara and Stanford played the majority of their home games at Kaiser Permanente Arena in neighboring Santa Cruz County.

The Battle 4 Atlantis tournament in Nassau, Bahamas was cancelled due to logistical issues associated with COVID-19. A new tournament known as the Crossover Classic is scheduled to be held at the Sanford Pentagon in Sioux Falls, South Dakota, and had invited almost all of the teams that had originally planned to compete in the Battle 4 Atlantis tournament (although five teams would later drop out).

On October 26, 2020, ESPN Events cancelled 10 early-season tournaments that it organizes. It had planned to hold them at the ESPN Wide World of Sports Complex in Orlando within a protected "bubble" (the same site had recently hosted the remainder of the 2019–20 NBA season under similar circumstances), but The Athletic reported that there had been disagreements over health and COVID-19 testing protocols that had been mandated by ESPN Events (in accordance with recommendations by the CDC), which were stricter than those being adopted by conferences.

Teams listed in bold type won "true road games", defined as games held at an opponent's regular home court (including regularly used alternate homes).

In addition to the above listed upsets in which an unranked team defeated a ranked team, there were eleven non-Division I teams to defeat a Division I team this season. Bold type indicates winning teams in "true road games"—i.e., those played on an opponent's home court (including secondary homes).

Each of the 31 Division I athletic conferences that played in 2020–21 ended its regular season with a single-elimination tournament. The team with the best regular-season record in each conference was given the number one seed in each tournament, with tiebreakers used as needed in the case of ties for the top seeding. The winners of these tournaments received automatic invitations to the 2021 NCAA Division I men's basketball tournament.

For this list, an "upset" is defined as a win by a team seeded 7 or more spots below its defeated opponent. This is more restrictive than the NCAA's official definition, in which a difference of 5 seed lines is sufficient to declare an "upset".
