The Second Avenue Subway (officially the IND Second Avenue Line; abbreviated to SAS) is a New York City Subway line that runs under Second Avenue on the East Side of Manhattan. The first phase of this new line opened on January 1, 2017, serving a projected 200,000 daily riders at three new stations between 96th Street and the 63rd Street Lines before connecting to the BMT Broadway Line and the rest of the subway system. The full Second Avenue Line, if and when funded, is planned to be built in three additional phases, allowing new portions to open before the entire line is completed between 125th Street and Hanover Square. The proposed full line would be 8.5 miles (13.7 km) long with 16 stations and a projected daily ridership of 560,000, costing more than $17 billion.

The line was originally proposed in 1919 as part of a massive expansion of what would become the Independent Subway System (IND). Work on the line never commenced, as the Great Depression crushed the economy. Numerous plans for the Second Avenue Subway appeared throughout the 20th century, but these were usually deferred due to lack of funds. The line was proposed to replace the Second Avenue and Third Avenue elevated lines. Although the new subway was not built, the elevated lines were demolished in 1942 and 1955, respectively. This left the Lexington Avenue Subway as the only rapid transit line on much of Manhattan's east side; it is by far the busiest subway line in the United States, with an estimated 1.3 million daily riders as of 2015.
