The 1992–93 Courage League National Division Three was the sixth full season of rugby union within the third tier of the English league system, currently known as National League 1. Otley finished the season as champions and were promoted to Courage League Division 2. Due to RFU changes to the English rugby union league system for the following season because of the introduction of Courage League Division 5, eight teams were relegated into Courage League Division 4.
