True professional baseball has not been played in Cuba since banned by the communist regime after the 1961 season, but there is a legacy of more than 70 years of continuous excellence by countless Cubans who played in the organized leagues of the island from 1878 to 1961. Scores of North Americans, white and black, and Latin Americans also played in Cuba during that time.

Biographical and season-by-season statistical information for the many hundreds of Cuban, North American and Latin American players who took part in the Cuban leagues from 1878 to 1961 has been compiled in this work. The time period is divided into three eras. The first is from 1878 to 1899, the primitive years of the Cuban league; the second, 1900 to 1933, when the league opened its doors to welcome foreign players; and the third, from 1934 to 1961, the golden age that made Cuba then the second power in organized baseball. Birth and death dates for each player (if they could be determined) are provided. The statistical information for players includes the number of games played, at bats, hits, doubles, triples, home runs, and season average. The statistical information for pitchers includes the number of games pitched, complete games, win-loss record, and winning percentage.
