1991–92 Cuban National Series

The 31st season of the Cuban National Series again featured a four-team postseason bracket tournament, with the semifinal round increased to best-of-five series. Two-time defending champion Henequeneros of Matanzas Province advanced to the championship series, but lost to Industriales of Havana in five games. The league makeup of 18 teams, each with a 48-game schedule, was unchanged from recent seasons. This was the final time the league fielded 18 teams.
