The Marlins ballpark is a proposed ballpark, to be built in the city of Miami, Florida, at the site of the former Miami Orange Bowl. Upon completion, the new stadium will become home to the Florida Marlins. Groundbreaking and construction are tentatively scheduled to start between November 2008 and January 2009, and the Marlins will move into their new home in April of 2011 or 2012. The stadium is anticipated to become the sixth Major League Baseball stadium to have a retractable roof, joining Rogers Centre, Chase Field, Safeco Field, Minute Maid Park and Miller Park.

With a seating capacity of 38,000, it will be the third-smallest stadium in Major League Baseball by official capacity, and the smallest by actual capacity. If the proposed Cisco Field and Rays Ballpark are built, then it will become third-smallest by actual capacity as well.
