1989–90 National Division 2

The 1989–90 National Division 2 (sponsored by Courage Brewery) was the third season of the second tier of the English rugby union league system, the Courage Clubs Championship, currently known as Champ Rugby. New sides included Waterloo (relegated from the top flight) and Rugby Lions and Plymouth Albion (promoted from tier 3).

Northampton, the champions, were promoted to the 1990–91 National Division 1 along with the runners–up Liverpool St Helens. It was the second time in three seasons that Liverpool St Helens won promotion from the second tier. Due to the expansion of the national divisions there was no relegation to the 1990–91 National Division 3.
