The 1991 Northeast Conference men's basketball tournament was held in March. The tournament featured seven teams; two teams, Mount St. Mary's and Robert Morris, were ineligible to participate. Robert Morris was penalized by the NCAA for institutional misconduct.[1] Saint Francis (PA) won the championship, their first, and as of 2022, only tournament title. They advanced to a play-in game against Fordham, which they won to advance to the 1991 NCAA tournament.
The NEC Men's Basketball Tournament consisted of a seven-team playoff format with all games played at the venue of the higher seed. The first seed received a bye in the first round.
