Marine Park is the name of a neighborhood and a public park in the New York City borough of Brooklyn, that lies between Mill Basin and Gerritsen Beach. The neighborhood is mostly squared off in area by Gerritsen Avenue, Flatbush Avenue, Avenue U and Kings Highway. The eponymous park is within the neighborhood. The neighborhood is largely made up of ethnic groups such as Italians, Irish, Greeks, and Jews. The area is part of Brooklyn Community Board 18.

A marine park is a park consisting of an area of sea (or lake) sometimes protected for recreational use, but more often set aside to preserve a specific habitat and ensure the ecosystem is sustained for the organisms that exist there. Most marine parks are designated by governments, and organized like 'watery' national parks.
