The GN convoys were a series of Caribbean convoys which ran during the Battle of the Atlantic in World War II.

[1] They take their name from the route: Guantanamo, Cuba to New York City[1] The GN series was the reverse of NG series that ran from August 1942 until 18 May 1945.

There were 207 GN convoys, comprising 4,313 individual ship listings and 18 escorts.

Some of the ships listed in a convoy did not always make the complete trip between Guantanamo and New York though, a few returned to Guantanamo, stopped at Charleston, South Carolina, or other ports.

[1] Only one convoy was attacked, 13 March 1943, by U-68, which resulted in two ships being lost.
