1985 saw the dawn of another new era in Saudi Arabian football with the league once again cut into two groups.
Al-Tai were once again promoted, replacing city neighbours Al-Jabalain who were relegated the previous season.
The winners and runners up of each six team group advanced to the finals phase to crown a champion, of which Al-Hilal won and defended the championship.
Teams finishing third and fourth in the group phases then played off for classification purposes and the teams finishing 5th and 6th played out a relegation pool.
Newly promoted Al Kawkab were relegated along with Al-Riyadh.
