Convoy SG-6 was a supply convoy of merchant and troop ships during the Second World War. It was one of the numbered SG Convoys from Sydney, Nova Scotia to Greenland. The convoy was split into two groups, with Chatham being escorted by USCG Mojave in a formation coded SG-6F, while the remainder were with SG-6S. SG-6F was found and attacked on 27 September 1942 by U-517, sinking Chatham, while U-165 contacted SG-6S, sinking 1 ship and damaging another. Convoy LN-6, which was a supply convoy from Quebec City to Goose Bay, was nearby and its escort HMCS Trail broke off to conduct rescue operations.
