The Cuban National Series (Spanish: Serie Nacional de Béisbol, or SNB) is a domestic baseball competition in Cuba. Formed after the dissolution of the Cuban League in the wake of the Cuban Revolution, the National Series is a part of the Cuban baseball league system.
For most of its existence, the National Series has existed as the top-level winter league in Cuba. From 2022 to 2024, it operated as a summer league, with the top six National Series teams qualifying for the Cuban Elite League (LEB). Starting with the 2025–26 season, SNB will return to a winter league schedule, while still qualifying teams to the LEB.
