The BMT Astoria Line (formerly the IRT Astoria Line) is a rapid transit line in the B Division of the New York City Subway, serving the Queens neighborhood of Astoria. It runs south from Ditmars Boulevard in Astoria to 39th Avenue in Long Island City above 31st Street. It then turns west and serves Queensboro Plaza over Queens Plaza.

The entire line is served by the N train at all times, joined by the W train only on weekdays during the day.^[2][3] It was built as part of the Dual Contracts and jointly operated by the Interborough Rapid Transit Company (IRT) and Brooklyn–Manhattan Transit Corporation (BMT) using IRT-sized cars until 1949, when the platforms were shaved to accept the wider BMT cars and joint service was discontinued.
