The 26th Cuban National Series was the second season the league held a postseason round-robin tournament to determine a champion. The four teams that qualified were the same as in the prior season: Vegueros from Pinar del Río Province, Industriales of Havana, Santiago de Cuba, and Villa Clara. Vegueros captured the championship by winning five of their six postseason games. The league's 18 teams and 48-game regular-season schedule were unchanged from the prior season.
