The 2006–07 Guinness Premiership was the 20th season of the top flight of the English domestic rugby union competitions, played between September 2006 and May 2007.

It was announced during the 2005-06 season that the 2006-07 competition would end two weeks early due to the 2007 Rugby World Cup in France, as England would be defending their title.

The Champions of this season were Leicester Tigers, beating Gloucester RFC 44–16 on 12 May in the Final at Twickenham, while the Northampton Saints were relegated.

The move has been explained as allowing clubs to capitalise on growing capacities and maximise refreshment income.
