2017–18 Premiership Rugby

The 2017–18 Aviva Premiership was the 31st season of the top flight English domestic rugby union competition and the eighth and final one to be sponsored by Aviva. The reigning champions entering the season were Exeter Chiefs, who had claimed their first title after defeating Wasps in the 2017 final. London Irish had been promoted as champions from the 2016–17 RFU Championship at the first attempt.

The competition was broadcast by BT Sport for the fifth successive season and with five games also simulcast free-to-air on Channel 5 for the first time. Highlights of each weekend's games were shown on Channel 5 with extended highlights on BT Sport.

Summary
Saracens won their fourth title after defeating Exeter Chiefs in the final at Twickenham after having finished second in the regular season table. London Irish were relegated after being unable to win their penultimate game of the season. It was the third time that London Irish have been relegated from the top flight since the leagues began and the first time since the 2015–16 Premiership Rugby season.

As usual, round 1 included the London Double Header at Twickenham, the fourteenth instance since its inception in 2004.

Teams
Twelve teams compete in the league – the top eleven teams from the previous season and London Irish who were promoted from the 2016–17 RFU Championship after a top flight absence of one year. They replaced Bristol Bears who were relegated after one year in the top flight.

Pre-season
The 2017 edition of the Singha Premiership Rugby Sevens was held on 28 and 29 July at Franklin's Gardens. For the first time all twelve Premiership teams featured together in one venue over two days. Teams were split into four pools of three which played each other in a round-robin basis with the tournament splitting into Cup, Plate and Bowl finals on the second day.

Regular season
Fixtures for the season were announced by Premiership Rugby on 7 July 2017. As is the norm, round 1 included the London Double Header at Twickenham. After success in 2016 a match would once again take place in the United States with Newcastle Falcons hosting Saracens at the Talen Energy Stadium in the Philadelphia suburb of Chester, Pennsylvania in round 3.

All fixtures are subject to change.
