The 2017 Super 8s were the third season of the Rugby Football League domestic competition in which the format of splitting teams after a certain number of games have been played. The format was employed across all three divisions and was used to decide championships, promotion and relegation. For the clubs in Super League XXII the split came after 23 games. The top eight clubs played each other once more before the top four team entered the playoffs for a place in the Super League Grand Final. In this group, points amassed during the regular season were carried forward to the Super 8 stage. The four teams finishing bottom of the Super League after 23 rounds went into a group of eight with the four teams who finished top of the Championship. Again the teams played each other once with the top three finishers after this stage plus the club who finished fifth playing in Super League XXIII while the other four will play in the 2018 Championship. This group of eight was also known as the Qualifiers and was the only Super 8 group in which points amassed during the regular season were not carried forward to the group stage. The other eight teams in the Championship competed for the Championship Shield with the top four going through to the Shield play-off semi-finals. The two teams finishing bottom of this group were relegated to League 1. In League 1 the top eight teams after the regular season of 15 games formed a group. The format for 2017 has been varied slightly from previous years in that the team finishing top of this Super 8 group will automatically be promoted to the Championship with the next four teams going through to the play-off semi-finals. Previously the top two teams played in the League 1 Grand Final with the winner being promoted and the loser going into the play-off semi-finals with the teams finishing third, fourth and fifth. The bottom eight teams in League 1 played each other for the League 1 Shield in a format identical to the Championship Shield except that there is no relegation from League 1.
