Miami Marine Stadium, Sports venue in Virginia Key, United States.

Miami Marine Stadium is a sports venue in Miami, located on Virginia Key along the Rickenbacker Causeway. The folded-plate roof rests on angled supports and opens the view toward the water, where races once took place.

The stadium opened in 1963 as the first place in the United States built for powerboat competition. Hurricane Andrew damaged the facility heavily in 1992, leading to its closure.

The stadium's official name honors Commodore Ralph Middleton Munroe, a Key Biscayne settler and boat designer. Its basin hosts the Miami International Regatta, run by the Miami Rowing Club since 1973, on a 1,500-meter, seven-lane course. The 1967 Elvis Presley film Clambake staged its climactic speedboat race here.

The stadium sits on Virginia Key, southeast of Downtown Miami, reached via the Rickenbacker Causeway. It is not open as a working venue; restoration began in early 2023 with repairs to damaged pilings. The structure stands behind a chain-link fence, so check access conditions before travelling.

After the closure, graffiti artists covered the concrete walls with colorful murals, turning the abandoned stadium into an informal open-air gallery. The artwork continues to draw curious visitors who walk among the empty rows of seats.
