The A Eighth Avenue Express is a rapid transit service in the B Division of the New York City Subway. Its route emblem, or "bullet", is colored blue since it is a part of the IND Eighth Avenue Line in Manhattan.

The A operates 24 hours daily between 207th Street in Inwood, Manhattan and Mott Avenue in Far Rockaway, Queens. During daytime hours, alternate service operates to and from Lefferts Boulevard in South Ozone Park, Queens. During rush hours, five scheduled trips in the peak direction operate from Beach 116th Street in Rockaway Park, Queens to Manhattan in the morning and back from Manhattan in the afternoon. Daytime service makes express stops in Manhattan and Brooklyn and all stops in Queens. Overnight service operates only between 207th Street and Far Rockaway, making all stops along the full route; during this time, a shuttle train (the Lefferts Boulevard Shuttle) operates between Euclid Avenue and Lefferts Boulevard.

The A provides the longest one-seat ride in the system—at 32.39 miles (52.13 km), between 207th Street and Far Rockaway—and a 2015 study indicated that it had a weekday ridership of 600,000.
