The 2025 Miami Marlins season marked the franchise's 33rd in the National League, played at LoanDepot Park under new manager Clayton McCullough, who was hired on November 11, 2024, as the team's 17th skipper. The Marlins significantly improved on their dismal 62–100 record from 2024, finishing 79–83 and claiming third place in the NL East. Despite their progress, playoff hopes officially ended on September 25 with a 0–1 loss to the Philadelphia Phillies. In a dramatic twist, the Marlins eliminated the New York Mets from postseason contention on the final day of the regular season—the third time in franchise history they've done so—paving the way for the Cincinnati Reds to clinch the last wild-card spot. The season followed an offseason shakeup in which former manager Skip Schumaker was not brought back after a 22-game regression from their 2023 campaign.
