The 1990–91 National Division 3 (sponsored by Courage Brewery) was the fourth season of the third tier of the English rugby union league system, the Courage Clubs Championship, currently known as National League 1. New teams to the division included Broughton Park, Clifton, Metropolitan Police and Morley, all of whom were promoted from tier 4, and due to reorganisation of the league structure at the end of the previous season, there were no relegated sides coming down from tier 2.

West Hartlepool finished the season as champions, two points clear of runners up Morley. Both sides would be promoted to the 1991–92 National Division 2, with Morley having been promoted for the second year running. At the other end of the table, the relegated sides were Vale of Lune and Metropolitan Police, dropping to the new look 1991–92 National Division 4 North and 1991–92 National Division 4 South respectively.
