The Koninklijke Nederlandse Baseball en Softball Bond (KNBSB) will organise the final phase of the Baseball European Championship 2025, which takes place on 20-27 September. The Neptunus Familiestadion, home to the most successful baseball club in Dutch history, Neptunus, will host the event. 

The local organising committee will be the Rotterdam Baseball Week Foundation, working closely with the KNBSB, Rotterdam Topsport, and Sportbedrijf Rotterdam.

Sixteen participating teams will be divided into four groups for the first phase, with two groups hosted in the Netherlands and two in a location yet to be announced. Each team will play three teams in their group, after which the top two teams from each group will advance to the final phase in the Netherlands.

The top 12 European teams will then compete in Rotterdam, beginning with the quarterfinals and culminating in the semifinals and finals.
