The 1997–98 Allied Dunbar Premiership One was the eleventh season of the first tier of the English league system, currently known as the Gallagher Premiership, and the first sponsored by Allied Dunbar, having previous been sponsored by Courage. Wasps were defending champions and Richmond and Newcastle Falcons the promoted sides.
Each team played each other twice, in a round robin system. Newly promoted Newcastle Falcons finished as league champions for the first time in their history, just one point clear of runners up Saracens. Only one side was relegated this season, with Bristol enduring a nightmare season and dropping down to the 1997–98 Allied Dunbar Premiership Two, in what would be their first season outside of the top flight since the leagues began.
