Neptunus is a professional baseball and softball club in Rotterdam, the Netherlands.

Neptunus is the most successful team in the Honkbal Hoofdklasse, the top level of professional baseball in the Netherlands. It has won the Holland Series 21 times. That includes seven consecutive titles from 1999 to 2005. During that dominant stretch, Neptunus also won the continental European Cup five consecutive times from 2000 to 2004. In 2010, the team set a single-season Dutch league record by winning 39 games.

The club evolved out of the multi-sports club SC Neptunus, which was founded on 1 June 1900. The baseball department was founded on 3 May 1943 and the softball department on 17 June 1973. Although the club fielded a football team in the past, Neptunus is primarily known for baseball and softball.[citation needed]

Following its 2014 championship season, the club signed a sponsorship contract for the 2015 through 2017 seasons with Curaçao and competes under the name Curaçao Neptunus. The club has revenues of 1 million euros.[citation needed]
