'TAG' was the designation of Allied convoys (together with a numerical suffix) plying the route from Trinidad via Aruba or in one case Curaçao, Netherlands West Indies, to Guantánamo, Cuba, and inaugurated as the replacement for the 'TAW' series started in July 1942, and as such reciprocals of the 'GAT' series (August 1942/May 1945).

The first of 205 such convoys was TAG.1 of 29 August/5 September 1942 with 31 merchant vessels and 10 escorts, and the last was TAG.206 of 13/18 May 1945 with just four merchant vessels.
