The K Eighth Avenue Local, earlier the AA, was a rapid transit service of the New York City Subway. Its route bullet was colored vivid blue on station signs, car rollsigns, and the official subway map since it ran on the IND Eighth Avenue Line.

The K operated during midday, evenings, and weekends, making all local stops between 168th Street in Washington Heights, Manhattan and World Trade Center in Lower Manhattan via Central Park West and Eighth Avenue in Manhattan. During late night hours, the A express made local stops on the IND Eighth Avenue Line. During rush hours, the C, formerly the CC, ran between Bedford Park Boulevard and Euclid Avenue, replacing the K as the local on Eighth Avenue.

A and AA service began on September 10, 1932 with the opening of the IND Eighth Avenue Line. The Independent Subway System (IND) used single letters to refer to express services and double letters for local services. The A ran express and the AA ran local, from 168th Street to Chambers Street/World Trade Center, known at the time as Hudson Terminal. The AA ran at all times, and it was extended to 207th Street during nights and on Sundays when the A did not run. When the Eighth Avenue Line was extended to Jay Street – Borough Hall on February 1, 1933 the AA was extended there, but only during the times when the A didn't run; it continued to terminate at Chambers Street when the A did run.
