The Manhattan Beach Branch, Manhattan Beach Line, or Manhattan Beach Division was a line of the Long Island Rail Road, running from Fresh Pond, Queens, south to Manhattan Beach, Brooklyn, New York City, United States. It opened in 1877 and 1878 as the main line of the New York and Manhattan Beach Railway. The tracks from Flatbush south to Manhattan Beach were removed from 1938 to 1941, while most of the rest is now the freight-only Bay Ridge Branch.
