LoanDepot Park was LEED certified as the greenest MLB park in 2012.The building is the sixth MLB stadium to have a retractable roof. With a seating capacity of 37,442, it is the third-smallest stadium in Major League Baseball by official capacity, and the smallest by actual capacity. The facility hosted a second-round pool of the 2013 World Baseball Classic, a first-round pool of the 2017 World Baseball Classic, the 2017 Major League Baseball All-Star Game, and the championship game of the 2023 World Baseball Classic. The park also hosts soccer matches, fundraising galas, and other events during the winter. It also hosted the Miami Beach Bowl from 2014 through 2016.

The stadium is designed in a neomodern form of baseball architecture. Prior to the construction of LoanDepot Park, the Marlins played home games at what was originally known as Joe Robbie Stadium in Miami Gardens, which was known by a number of different names during the Marlins' tenure there. Joe Robbie Stadium was built in 1987 as home to the Miami Dolphins of the National Football League (NFL), and was designed as a multi-purpose stadium built primarily for football, but it's design also accommodated baseball and soccer. Dolphins founder Joe Robbie believed it was a foregone conclusion that MLB would come to South Florida, so he wanted the stadium designed to make any necessary renovations for baseball as seamless as possible. The Marlins arrived in 1993 and during their time at the stadium, the Marlins drew more than 3 million people in their inaugural season and also won two World Series titles, in 1997 and 2003. The stadium continues to be home to the Dolphins, and since 2008, the Miami Hurricanes from the University of Miami.
