Howard Terminal Ballpark was a proposed baseball stadium to be built in the Jack London Square neighborhood of Oakland, California. If approved and constructed, it would have served as the new home stadium of the Oakland Athletics of Major League Baseball (MLB), replacing the Oakland Coliseum. The 34,000-seat stadium was the last of several proposals to keep the Athletics in Oakland. The site is currently a parcel of land owned by the Port of Oakland. After securing the site, the Athletics planned to have the stadium built and operational after the team's lease expired at the Oakland Coliseum in 2024.
