'NY' was the designation of Allied convoys (together with a numerical and sometimes a literal suffix) plying the route from New York City to a number of destinations mainly in the Caribbean and the UK (August 1943/November 1944).

The NY.86A and NY.109A convoys sailed from Trinidad to Guantánamo and from Rockland to New York City respectively.

The first of the 57 such convoys was NY.21 of 22/31 August 1943 from New York City to Belfast Lough, Northern Ireland, with four US naval vessels in the form of the escort carrier Block Island and destroyers Dupont, Ellis and Herbert, and the last was NY.134 of 10/16 November 1944 from New York City to Cristobal, Panama, with the 8,222-ton US commissioned stores ship Polaris.
