The 1991 NCAA basketball tournament was the 67th season in the Philippine National Collegiate Athletic Association (NCAA). The season opens on August 3 at the Araneta Coliseum and ended on October 16 with the Mapua Cardinals winning back-to-back championships in the Seniors division and won their 5th NCAA crown.
A team wins both rounds. In that case, the winning team automatically wins the championship.
A third team has a better cumulative record than both finalists. In that case, the third team has to win in a playoff against the team that won the second round to face the team that won in the first round in a best-of-3 finals series.

Mapua Cardinals wins the second round flag and forces a best-of-three title playoffs with first round winner San Beda College by downing the Red Lions on the last day of the eliminations on October 2.
Finals Most Outstanding Player: Benny Cheng (Mapúa Cardinals)
In Game 1, Mapua had their biggest lead at 96-81 with 3:20 remaining. But the Red Lions' unlikely trio of Reynaldo Dionisio, Cornelio Manucat and last year's junior MVP Vincent Largo put San Beda to within 90-96 in the last 1:43. A triple by Olegario Topacio which beat the shotclock and two free throws by Reuben dela Rosa got the Cardinals off the hook.
With reserves Cornelio Manucat, Reynaldo Dionisio, Renato Morano and Jose Ramil Espina thrown into the limelight of championship action, the Red Lions broke away at 91-78 in the last 2:25 of Game 2. A 14-4 Mapua counter triggered by Olegario Topacio and Winchester Lemen put the Cardinals to within 92-95 in the last 45 seconds.
Cardinal slotman Benito Cheng beat all rebounders for a follow-up in the final five seconds of Game 3 and an awry pass spoiled the Red Lions' last offensive. There was no San Beda timeout and what ensued was a quick inbound to Cornelio Manucat who dribbled toward the centerline before issuing a breast-pass to a streaking Reynaldo Dionisio. The pass was too strong and a bit high, lipping Dionisio's fingertips before going out of bounds with a stream of Mapua supporters entering the court at the buzzer.
Finals Most Outstanding Player: Tyrone Bautista (San Beda Red Cubs)
The San Beda Red Cubs won Game 1 off the heroics of Tyrone Bautista, Emerson Roque and Cesar Tolentino, who combined for 53 points. The Red Robins tied the series on Game 2. On the deciding Game 3, Bautista led the Red Cubs anew, winning back-to-back titles.
