2017–18 British and Irish Cup

The 2017–18 British and Irish Cup is the ninth and final season of the annual rugby union competition for second tier, semi-professional clubs from Britain and Ireland. Munster A are the defending champions having won the 2016–17 final against Jersey Reds 29–28 at Irish Independent Park, Cork on 21 April 2017. The format of the competition is similar to last season with Scottish clubs not competing. For the third consecutive season the four Welsh teams are the reserve sides of the teams competing in the Pro14 competition instead of clubs from the Welsh Premier Division.

Competition format
The competition format is a pool stage followed by a knockout stage. The pool stage consists of five pools of four teams playing home and away matches. The top side in each pool, plus the three best runners-up, progress to the knockout stage. The eight quarter-finalists are ranked, with top four teams having home advantage. The four winning quarter-finalists progress to the semi-final draw. Most of the matches are played on the same weekends as the European Champions Cup and European Challenge Cup. First round matches begin on 13 October 2017 and the final will be held in April 2018.

Participating teams and locations
The allocation of teams is as follows:
 * 🏴󠁧󠁢󠁥󠁮󠁧󠁿 – twelve clubs from RFU Championship
 * 🇮🇪 – four Irish provinces represented by 'A' teams
 * 🏴󠁧󠁢󠁷󠁬󠁳󠁿 – four Welsh regions represented by Premiership Select teams.

Knock-out stage
The eight qualifiers are seeded according to performance in the pool stage. The four top seeds hosted the quarter-finals against the lower seeds, in a 1 v 8, 2 v 7, 3 v 6 and 4 v 5 format. However, if two teams qualify from the same group they can not be drawn together. Therefore, Leinster A cannot be drawn against Doncaster Knights. Teams are ranked by:
 * 1 – competition points (4 for a win, 2 for a draw)
 * 2 – where competition points are equal, greatest number of wins
 * 3 – where the number of wins are equal, aggregate points difference
 * 4 – where the aggregate points difference are equal, greatest number of points scored
