The 1997–98 Premiership 1 was the twelfth season of the top tier of the English rugby union league system, currently known as Premiership Rugby, and the second to be sponsored by Allied Dunbar, having previous been sponsored by Courage Brewery. Newcastle Falcons were the defending champions and Bedford, London Scottish and West Hartlepool the promoted sides.
Leicester Tigers finished the season as champions for the third time (and first title since 1995), while West Hartlepool were relegated to as the bottom place side, dropping to the 1999–00 Premiership 2. 9th place Richmond and 12th London Scottish were placed into administration at the end of the campaign, merging with London Irish, and thus did not compete in the subsequent season.
