The Holland Series is the annual championship series of the highest level of professional baseball in the Netherlands. It is the conclusion of the postseason of Honkbal Hoofdklasse, played between the two winners of the league's playoffs. The series was played for two years in the 1970s, then annually beginning in 1987.

The Holland Series championship is determined through a best-of-seven game playoff. Currently, six teams qualify for the playoffs, with the top two teams in the Hoofdklasse regular season earning a bye in the Wildcard round.

Neptunus in Rotterdam has won 21 Holland Series championships, more than any other Dutch club.
