Our Story

Celebrating Mets History & Fan Passion

The Ultimate Mets Database began in 1999 by an ultimate Mets fan and it has only grown from there. In 2026, control of this site was transferred to a new group of Mets fans. Our mission is to connect Mets fans everywhere with the legacy, statistics, and unforgettable moments that define our team.
