The 1919–20 NCAA men's basketball season began in December 1919, progressed through the regular season, and concluded in March 1920. a Dartmouth was unable to field a team, so Eastern Intercollegiate Basketball League conference play was informal in 1919–20 and no official champion was declared.
However, had a champion been named, Penn would have won the regular-season championship with a 7–1 conference record.
Among independents that played at least 10 games, Montana State (13–0), North Dakota (16–0), Southwestern (14–0), and Westminster (17–0) were undefeated, and Millikin (22–1) and Nebraska (22–2) finished with the most wins.

Premo and computer programmer Phil Porretta researched teams from the 1895–96 through the 1947–48 seasons, reviewing results, opponents, and margins of victory to create retroactive polls for the seasons predating the debut of the AP Poll.
The Helms Athletic Foundation later retroactively selected a list of All-Americans for the 1919–20 season.
