2017–18 London & South East Premier

The 2017–18 London & South East Premier season is the 31st season of level 5 in the London and South East region of English rugby union. It consists of thirteen teams from England and one from the Channel Island of Guernsey. It will be the first season organised under the London & South East Premier title following the rename from "National League 3 London & SE" during the off-season. This decision was made by the Rugby Football Union owing to the fact that it was felt that the league title was misleading as it was not a nationwide league but was instead the highest level of rugby in the London and South East region.
