This was a change from previous seasons, which culminated in a knock-out format competition leading to a final.

The tournament was a knock-out format, played over one leg with the first team drawn in each fixture hosting the match.

The quarter-finals took place on the first weekend of October, with Edinburgh, Glasgow and Connacht winning their games.

Rather than continuing with the automatic home advantage for the highest-seeded teams remaining in the semi-finals, the fixtures were instead decided by a draw.

The final took place on 14 May at Lansdowne Road and saw Munster beat the Scarlets 27–16 to win the second Celtic Cup.
